Optimizing The Cleaning Plan Of A Solar Pv System Plant

Study Objective:

This study addresses a critical operational challenge for photovoltaic (PV) plants in arid environments: soiling (dust accumulation). In desert climates like the UAE, soiling can reduce energy output by up to 30–60% if left unmanaged. The objective is to optimize the cleaning schedule for a utility-scale solar plant by balancing two competing costs: cleaning expenses vs. revenue loss from soiling-induced energy degradation. The study develops a mathematical optimization model to determine which rows to clean, and when, over a given planning horizon.

Methodology:

• Site: Masdar City Solar PV Plant, Abu Dhabi (10 MW capacity; 87,780 panels; 40 rows analyzed).
• System: Fixed-tilt CdTe thin-film panels; cleaned by Ecopia H4 robotic dry-cleaning systems (3 robots available).
• Horizon: 90 days (daily cleaning decisions).
• Modeling Approach:
  • Environmental Inputs: NASA MERRA-2 irradiance, temperature, soiling rate data (0.02–0.09%/day).
  • Energy Yield Modeling: Equations for tilted surface irradiance, PV cell temperature, and maximum clean energy (EmaxClean).
  • Soiling Dynamics: Loss rate (LR) accumulates daily unless reset by cleaning.
  • Optimization: Mixed-Integer Programming (MIP) solved via IBM CPLEX. Objective function minimizes total cost = cleaning cost + energy loss cost.
  • Constraints: Daily cleaning capacity (C=3 rows/day); loss rate reset logic.
• Sensitivity Analysis: Tested variations in robot count, soiling rate, cleaning cost, and energy tariff.

Key Findings:

1. Optimal Cleaning Schedule:

• Cleaning intervals of 3 to 20 days are optimal.
• Most rows should be cleaned 6 or 7 times over 90 days.
• Total optimal cost: USD 7,987 (combining cleaning labor and soiling loss).

2. Energy Loss Dynamics:

• Without cleaning, loss rates accumulate linearly; each cleaning event resets loss near zero.
• The model dynamically triggers cleaning when accumulated loss justifies the intervention cost.

3. Sensitivity Insights:

• Soiling rate and energy price are the dominant cost drivers. When both are low, cleaning is not economically justified.
• Cleaning cost is a secondary factor; the model tolerates moderate cost increases by extending intervals.
• More robots enable shorter intervals and lower energy loss, but capital costs must be evaluated separately.

4. Comparison to Literature:

• Robotic dry cleaning (this study) achieves 90–97% cleaning efficiency, 0–20% energy gain, at USD 0.11–0.25/m², with zero water use—superior to manual/water-based methods for arid regions.

Conclusions:

• A fixed-interval cleaning policy (e.g., every 14 days) is suboptimal. Optimal schedules are dynamic and row-specific, responding to soiling accumulation and economic thresholds.
• The developed MIP framework provides prescriptive, operational guidance for plant managers, moving beyond heuristic or simulation-only approaches.
• The model is adaptable to other PV technologies (monocrystalline, polycrystalline, thin-film) and geographic contexts with modified input parameters.

Managerial & Policy Implications:

1. For Plant Operators:

• Implement data-driven cleaning schedules rather than calendar-based routines.
• Invest in real-time soiling monitoring (sensors, drones) to feed optimization models.
• Evaluate robot fleet size considering both operational savings and capital expenditure.

2. For Utility-Scale Project Developers:

• Include cleaning optimization in O&M contract design and performance guarantees.
• Use the model to benchmark cleaning service-level agreements (SLAs).

3. For Policymakers (e.g., UAE Energy Strategy 2050):

• Support R&D into low-water, automated cleaning technologies.
• Encourage performance-based standards that reward adaptive maintenance.

Methodological Contributions:

• First application of MIP with CPLEX to row-level cleaning scheduling in a 10 MW desert PV plant.
• Integration of physical energy yield models (irradiance, temperature, soiling) with economic optimization.
• Transparent handling of soiling rate variability and capacity constraints.

Limitations & Future Research:

• Optimality gap: 21.65%—solution is near-optimal but not proven optimal; longer run times or heuristic methods (e.g., NSGA-II) could improve.
• Spatial homogeneity assumption: Soiling rate treated as uniform across rows; real-world spatial variation not captured.
• No empirical validation: Results not yet validated against PVsyst simulations or SCADA data (planned).
• Robot investment cost excluded: Model optimizes operational cleaning cost only; total cost of ownership analysis needed.

Overall Significance:

This study provides a rigorous, generalizable optimization framework for one of the most pressing operational challenges in desert solar energy. By shifting from fixed-interval to condition-based, cost-optimized cleaning, it offers a pathway to improve plant profitability, reduce water usage, and support renewable energy targets in arid climates. The methodology is transferable to other large-scale PV plants globally and contributes to the growing field of data-driven operations and maintenance (O&M) in renewable energy systems.

Transforming Smart Homes Via P2p Energy Trading Using Robust Forecasting And Scheduling Framework

Study Objective:

This research addresses the growing complexity of decentralized energy systems by proposing a novel Peer-to-Peer (P2P) Home Energy Management System (HEMS) . The objective is to enable prosumers and consumers to trade energy directly, reducing reliance on centralized utilities. To achieve this, the study develops a three-stage hybrid AI framework for accurate demand and generation forecasting, optimal load scheduling, and real-time supply-demand balancing in P2P networks.

Methodology:

The proposed framework integrates three advanced computational techniques in a sequential pipeline:

1. Stage 1 – Feature Selection (WHO):

• Wild Horse Optimization (WHO) is applied to reduce dimensionality and select the most relevant features from historical energy, environmental, and market data.
• This eliminates noise, improves model interpretability, and reduces computational load.

2. Stage 2 – Forecasting (Bi-LSTM with Attention):

• A Bidirectional Long Short-Term Memory (Bi-LSTM) network, enhanced with an attention mechanism, is used to predict short-term energy demand and PV generation.
• Bi-LSTM captures both past and future temporal dependencies, significantly improving forecast accuracy over unidirectional models.

3. Stage 3 – Hyperparameter Optimization (GHO):

• Grasshopper Optimization (GHO) fine-tunes the Bi-LSTM hyperparameters (learning rate, layers, dropout, etc.) to maximize performance and adapt to dynamic conditions.

4. Scheduling & Control:

• A probabilistic closed-loop control model maintains load flow balance between supply Pe(t) and demand Le(t).
• A P2P transaction model optimizes energy exchange between paired homes, minimizing total energy cost and battery degradation while respecting bidirectional flow constraints.

Key Findings:

1. Forecasting Accuracy:

• The WHO-Bi-LSTM-GHO model was tested on three residential prosumers (Homes A, B, C) with varying demand (5–12 kW) and PV generation (1.75–10 kW).
• The model achieved tight alignment between forecasted and actual values, demonstrating high precision even under uncertainty.

2. P2P Trading Simulation:

• Home C (excess generation) supplied deficit power to Homes A and B during critical intervals (e.g., 4200h, 6000h).
• The closed-loop controller successfully minimized randomness Ap(t) by synchronizing a0 and a(t), achieving load flow equilibrium.

3. Comparative Validation:

• The framework was benchmarked against existing literature and a real-world testbed (Benguerir, Morocco).
• Results confirm that the hybrid model outperforms single-algorithm approaches in scalability, adaptability, and economic efficiency.

4. Scalability & Interoperability:

• WHO ensures efficient data handling via dimensionality reduction.
• Bi-LSTM provides modular, scalable forecasting suitable for expanding smart home networks.
• GHO enables real-time parameter adaptation, ensuring robustness across regulatory, environmental, and market changes.

Conclusions:

• The proposed WHO-Bi-LSTM-GHO framework offers a comprehensive, scalable, and adaptive solution for P2P energy trading in smart homes.
• It addresses critical gaps in existing literature:
  • Lack of integrated feature selection + forecasting + optimization pipelines.
  • Insufficient handling of probabilistic uncertainty in P2P transactions.
  • Poor scalability in multi-cluster, multi-operator networks.
• The framework is technology-agnostic and can be deployed across diverse PV-battery systems, regulatory environments, and market structures.

Managerial & Policy Implications:

1. For Prosumers/Homeowners:

• Enables autonomous energy trading, reducing electricity bills and increasing ROI on PV-battery systems.
• Provides real-time scheduling recommendations for shiftable appliances.

2. For Utilities & Grid Operators:

• Reduces peak load stress through localized P2P balancing.
• Offers a decision-support tool for demand response aggregation and grid stability.

3. For Policymakers:

• Supports the development of regulatory sandboxes for decentralized energy markets.
• Provides a data-driven framework for designing fair P2P tariff structures and interoperability standards.

Limitations & Future Research:

• Computational Complexity: Joint optimization across multiple homes increases processing time; future work should explore federated learning and edge computing to distribute the load.
• Real-World Validation: While validated against a Moroccan testbed, broader pilot studies across different climates and grid configurations are needed.
• Battery Degradation Modeling: The current model includes a simplified degradation cost; future iterations should integrate electrochemical aging models.
• Multi-Home Simultaneous Trading: The current study assumes paired transactions; future work should extend to n-party simultaneous P2P auctions.

Overall Significance:

This study presents a paradigm shift in smart home energy management—moving from passive consumption and utility-centric control to active, AI-driven P2P collaboration. By integrating bio-inspired optimization, deep learning, and probabilistic control, it delivers a holistic, future-proof architecture for the next generation of decentralized, carbon-neutral energy communities. The framework is directly applicable to smart city initiatives, virtual power plants, and transactive energy markets, positioning it as a foundational contribution to the field of cyber-physical energy systems.

Cleaning Products: Their Chemistry, Effects On Indoor Air Quality, And Implications For Human Health

Study Objective:

This comprehensive review synthesizes the current scientific evidence on the chemical composition of cleaning and disinfecting products, their impact on indoor air quality (IAQ), and the associated human health risks. It addresses a critical knowledge gap heightened by the COVID-19 pandemic, during which the frequency and intensity of cleaning increased dramatically worldwide. The review aims to provide actionable recommendations for reducing harmful exposure and to identify future research priorities.

Methodology:

• Systematic Literature Review: 26 search terms across PubMed, Google Scholar, Scopus, and Web of Science (2013–2024), supplemented by key older literature.
• Final Dataset: 202 studies included after multi-stage screening and expert consultation.
• Scope: Residential and public buildings (schools, offices, healthcare); occupational and non-occupational exposure; chemical, particulate, and biological impacts.

Key Findings:

1. Chemistry of Cleaning Products & Indoor Air Quality (IAQ)

• Hazardous Ingredients: Cleaning products contain surfactants, acids/bases, solvents, preservatives (isothiazolinones, formaldehyde releasers), fragrances (26 EU allergens), and bleaching agents (hypochlorite, H₂O₂).
• Reactive Chemistry: Many products undergo unintended chemical reactions indoors:
  • Terpenes + Ozone → Secondary Organic Aerosols (SOAs), formaldehyde, and respiratory irritants (Criegee mechanism).
  • Bleach (HOCl) → Forms trichloramine (NCl₃), dichlorine monoxide (Cl₂O), nitryl chloride (ClNO₂), and chlorinated VOCs.
  • Hydrogen Peroxide: High emissions persist for hours; reacts with VOCs to form secondary pollutants.
• Secondary Organic Aerosols (SOAs): Cleaning activities generate ultrafine particles (<100 nm) at concentrations up to 1.25 × 10⁵ particles/cm³, comparable to cooking emissions.

2. Exposure & Human Health Effects

• Occupational Exposure (Cleaners, Healthcare Workers):
  • Strong causal evidence for increased risk of asthma (new-onset and exacerbation), rhinitis, and COPD.
  • Spray application is the most hazardous delivery method.
  • Cleaning work is associated with accelerated lung function decline and all-cause mortality in some cohorts.
• Residential Exposure (Adults & Children):
  • Children are particularly vulnerable due to higher breathing rates, near-floor activity, and hand-to-mouth behavior.
  • Frequent use of cleaning products linked to persistent wheezing, asthma onset, rhinitis, and reduced lung function.
  • Prenatal and early-life exposure is associated with respiratory morbidity.

• Pandemic-Related Overuse: 47% of users reported new health symptoms (skin irritation, shortness of breath); 33% of U.S. adults engaged in unsafe cleaning practices during COVID-19.
• Endocrine & Cellular Effects: QACs detected in human blood correlate with inflammatory cytokines, mitochondrial dysfunction, and cholesterol disruption.

3. Means to Reduce Exposure (10 Key Recommendations)

1. Optimize Product Selection: Avoid terpene-based cleaners; prefer ready-to-use H₂O₂ over bleach; eliminate air fresheners.
2. Schedule Cleaning When Unoccupied: Especially in schools/offices; allow ≥5 hours re-entry time.
3. Improve Ventilation: Increase air exchange during and after cleaning.
4. Use Personal Protective Equipment (PPE): Gloves (task-matched) and respiratory protection for high-risk tasks.
5. Maintain Tools Properly: Remove cleaning supplies from occupied spaces immediately.
6. Educate Users: Raise awareness of product hazards and safe practices (lay users and professionals).
7. Enforce Clear Labeling: Improve hazard communication on consumer products.
8. Adopt Alternative Technologies: Probiotic cleaning systems show promise in healthcare (reduced HAI without toxic chemistry).
9. Regulate Fragrance Allergens: Strengthen disclosure requirements.
10. Implement Targeted Hygiene: Focus on high-risk moments/sites to balance infection control and chemical exposure.

Conclusions:

• Cleaning is both essential and hazardous. The benefits of hygiene must be weighed against the proven respiratory and systemic risks of cleaning chemicals.
• Current cleaning practices are not optimized for health. Most protocols prioritize disinfection efficacy over occupant and worker safety.
• Indoor air chemistry is complex and reactive. Cleaning introduces precursors that form secondary pollutants long after application ceases.
• Vulnerable populations (children, cleaners, asthmatics) require immediate protection through policy, product reformulation, and behavioral change.

Implications for Policy & Practice:

• Regulators (EU CLP, EPA): Should accelerate substitution of hazardous substances (e.g., QACs, isothiazolinones, certain fragrances) and mandate clearer consumer labeling.
• Facility Managers: Implement procurement policies favoring low-emission, fragrance-free, non-reactive products. Schedule cleaning during unoccupied periods.
• Healthcare Administrators: Evaluate trade-offs between disinfection efficacy and staff/patient exposure; consider probiotic cleaning systems where evidence supports.
• Public Health Authorities: Launch awareness campaigns on safe cleaning, particularly targeting parents, schools, and domestic workers.
• Product Manufacturers: Reformulate to reduce terpene content, eliminate hazardous preservatives, and develop non-chemical disinfection technologies.

Research Gaps & Future Directions:

• Long-term health effects of chronic low-dose exposure to cleaning chemicals (especially QACs, fragrances, and SOAs).
• Real-time personal exposure monitoring (vs. room-averaged measurements).
• Intervention studies evaluating the health impact of switching to greener or alternative cleaning systems.
• Child-specific exposure assessment integrating inhalation, dermal, and ingestion pathways.
• Mechanistic studies on TH2-adjuvant effects and endocrine disruption.

Overall Significance:

This review provides a definitive, interdisciplinary synthesis of the chemistry, exposure science, and epidemiology of cleaning products. It demonstrates that cleaning is not a chemically inert act—it actively transforms indoor air and leaves a persistent chemical and biological legacy. By bridging the gap between molecular reactions and population health, the authors provide a roadmap for evidence-based, health-centered cleaning that preserves hygiene without compromising indoor environmental quality.
