Deployment strategy of PV-ESS for industrial and commercial electricity users with consideration of carbon benefits

Journal of Renewable and Sustainable Energy, Год журнала: 2025, Номер 17(2)

Опубликована: Март 1, 2025

As the global shift away from fossil fuels intensifies, distributed photovoltaics (PV) have emerged as most significant and swiftly expanding renewable energy source accessible to end-users due their convenience in flexible deployment. Coupled with steep decline storage costs, co-deployment of PV systems (PV-ESS) has become a preferred option for electricity users, especially large ones. The PV-ESS investment decision-making model is encountering new obstacles stemming gradual withdrawal governmental subsidies swift transition carbon markets. To address pressing requirement industrial commercial this paper introduces an improved capacity configuration that incorporates benefits into its considerations. First, we constructed cost-benefit analysis users investing PV-ESS. Second, proposed optimization maximizing annual returns objective function. Finally, validate model, conducted case studies across various typical scenarios explore optimal configurations returns. results indicate within existing market framework, achieving return on challenging. However, incorporating can significantly enhance system Specifically, emissions decrease by 23.84% under low price scenario 50.91% high scenario, while net present value increases 67.98% 941.96%, respectively. This study shed fresh insights policy-makers deployment

Long-term Power Generation Prediction in Photovoltaics Using Machine Learning-based Models

Romanian Journal of Information Science and Technology, Год журнала: 2025, Номер 28(1), С. 39 - 50

Опубликована: Март 14, 2025

The research in the field of renewable energy has taken centre stage study reliable and effective photovoltaic (PV) systems. These systems are essential to a future powered by energy, where solar radiation is directly converted into electrical power. However, arrays have limited conversion efficiency. Hence, highly accurate forecasting strategies required mitigate impact this challenge. This focuses on proposing serial algorithms that combine machine learning global optimization solve stochastic problems. Gated Recurrent Unit (GRU) architecture, Support Vector Machine (SVM) for Regression (SVR) models Differential Evolution algorithm (DE) used developing forecast grid power generation across environmental variations. Initially, four GRU-SVR will be trained address prediction seasonal evolution. Afterwards, hybrid approach GRU-SVR-DE strategy defined integrate models, providing robust PV generation. In end, performances predictions analyzed demonstrate accuracy long-term forecasts.

Technological innovation structure and driving factors of China’s photovoltaic industry: based on patent innovation network

International Journal of Low-Carbon Technologies, Год журнала: 2024, Номер 19, С. 1596 - 1609

Опубликована: Янв. 1, 2024

Abstract Photovoltaic (PV) industry is a strategic emerging in China, which provides risk resistance and autonomy for energy security by its technology innovation structure. The article conducts comparative study on the technological of PV between China major powers to master structure China’s industry. For this purpose, analyzes relative evolution data above profiles employing social network analysis (SNA). Multiple linear regression was applied analyze driving factors mechanism. results show that: (i) Compared with other economies, characterized hysteresis, rapid advancement, chain bias towards midstream downstream. (ii) connection whole gradually tends be direct diversified, but tightness integral decreasing. (iii) siliceous resource retention biggest force development industry, followed investment intensity research developement (R&D) corresponding Based findings, puts forward countermeasure recommendations.
