Optimal operation and locating method of new energy building with shared charging service

Abstract

In order to cope with global climate change, an electric vehicle (EV) and new energy building are constantly being innovated and improved. With the popularity and application of big data and Internet of Things, the new energy building with available charging piles may also become a charging station, which can solve the problem of difficult charging of EVs and promote the local energy consumption of the building. Therefore, this study proposes a shared charging concept for buildings, that is, shared photovoltaic, charging, and energy storage building (sPCEB). First, based on the analysis results of big data in cities or settlements of people, a locating method of the sPCEB system is introduced, and further proposes an optimal operating strategy that maximizes the combined benefit of the building. The efficiency and effectiveness of the proposed methods are verified by simulation.

Islanding detection method for microgrids based on CatBoost

“…The power quality in MGs is the key to determining whether MGs can operate stably. When the power quality does not meet the requirements or the power supply is interrupted due to the failure of distribution networks, the DGs will continue to supply the load, thus forming an islanding state of the MGs (Wang et al, 2022a;Liu et al, 2022). After the occurrence of islanding, the DGs should take corresponding control measures to change their inverter control mode, and even implement the corresponding load shedding strategy when the power shortage is serious.…”
