“…Root Mean Square Error (RMSE) quantifies the average magnitude of prediction errors, with smaller values indicating better predictive accuracy. Mean Absolute Percentage Error (MAPE) gauges the average percentage difference between predictions and actual values, reflecting the model's average precision [27][28][29]. The definitions of the above performance indicators and the representation of the equations are presented in Table 2.…”

Photovoltaic (PV) power generation exhibits stochastic and uncertain characteristics. In order to improve the economy and reliability of a photovoltaic-energy storage system (PV-ESS), it is crucial to optimize both the energy storage capacity size and the charging and discharging strategies of the ESS. An optimal scheduling model for PV-ESS is proposed in this paper, comprehensively considering factors in terms of energy cost and charging/discharging constraints of the PV-ESS. Moreover, the model employs a particle swarm optimization-backpropagation (PSO-BP) neural network to predict the PV power using historical generation data from a factory in Xiamen. The proposed two PV-ESS scheduling strategies are compared under three weather conditions. In the demand management strategy, the ESS can flexibly respond to different weather conditions and load demand changes, and effectively reduce the electricity cost for users.

The world’s energy demand is on the rise, leading to an increased focus on renewable energy options due to global warming and rising emissions from fossil fuels. To effectively monitor and maintain these renewable energy systems connected to electrical grids, efficient methods are needed. Early detection of PV faults is vital for enhancing the efficiency, reliability, and safety of PV systems. Thermal imaging emerges as an efficient and effective technique for inspection. On the other hand, evidence indicates that monitoring inverters within a solar energy farm reduces maintenance expenses and boosts production. Optimizing the efficiency of solar energy farms necessitates comprehensive analytics and data on every inverter, encompassing voltage, current, temperature, and power. In this study, our objective was to perform two distinct fault analyses utilizing image processing techniques with thermal images and machine learning techniques using inverter and other physical data. The results show that hotspot and bypass failures on the panels can be detected successfully using these methods.

The I-V curves of solar photovoltaic (PV) systems have been widely used as a tool to determine their electrical operation. Usually, I-V curves are described by means of three cardinal points: the short-circuit point ( 0 , I sc ) , the open-circuit point ( V oc , 0 ) , and the maximum power point ( V mp , I mp ) . In this context, to study the I-V curves, the Single-Diode Model (SDM) is often used. In this manuscript, we present a practical approach for determining the parameters domain of the SDM given a set of cardinal points. An in-depth mathematical analysis showed that the cardinal points must satisfy the following inequalities V oc / 2 < V mp < V oc and I sc / 2 < I mp < I sc . Then, it is possible to implicitly represent the SDM by means of one single parameter in a thoroughly chosen coordinate space. Based on these theoretical results, a fast computational algorithm for calculating the SDM parameters limits is proposed. The algorithm has been computer-tested using 40 000 synthetically generated maximum power points which are processed in about one minute of the CPU time on a standard laptop computer. Moreover, as a practical application, the California Energy Commission database is analyzed using the proposed algorithm.
