Abstract The power allocation of adjustable resources in the source-grid-load-storage system is an important component for the stable operation of the system. To address the problem of stability degradation caused by insufficient consideration of dynamic response differences of adjustable resources in traditional source-grid-load-storage system power allocation, a control method for the source- grid-load-storage system based on multi-mode power allocation is proposed. Adjustable resources are devided into fast response resources (such as energy storage batteries, supercapacitors) and slow response resources (such as wind power, photovoltaics), which are verified through hardware in the loop simulation experiments, using stepwise and target-based power allocation modes respectively. Simulation results show that the proposed method reduces the regulation time of energy storage systems by 70.92%, photovoltaic systems by 51.84%, and significantly reduces overshoot and underregulation. This method effectively improves the stability of the source-grid-load-storage system through a differentiated power allocation strategy, and has engineering application value.

Key words： source-grid-load-storage system multi-mode power allocation target-based power allocation mode stepwise power allocation mode stability
