SHANG Liqun,WANG Shuo
Abstract:As the proportion of installed photovoltaic(PV)capacity increases year by year,accurate predictionof PV output and the realization of group control and management of PV clusters become crucial. A multi-site PVoutput prediction method that integrates deep fusion of graph convolutional neural network(GCN),lon...

Abstract:In order to further improve the power density and output performance of the transformerlessmedium-voltage power quality control device,a partial submodule multiplexing modular multilevel converter(PSM-MMC)topology and its control strategy were proposed. The PSM-MMC was composed of four groups ofarm submodul...

Abstract:In response to the intermittency and uncertainty of wind power generation,which result in low windpower utilization and high electricity purchase costs in microgrids,an intelligent dispatch strategy based on aresidual-like soft actor-critic(R-SAC)algorithm was proposed. The scheduling problem was formulated...

Abstract:The contact electrical contact fault of gas insulated switchgear(GIS)will affect its electricalperformance. A multi-physics coupling model of GIS contact vibration was first established to address the difficultyin diagnosing contact faults. An experimental platform for high-current detection of GIS was buil...
