Research on Optimal Scheduling of Wind-PV-Hydro-Storage Power Complementary System Based on BAS Algorithm

Abstract

In order to solve the impact of massive wind power and solar power's grid-connection volatility on the safe and stable operation of the power grid.By analyzing the complementary characteristics of the wind power, solar power, hydro power and pumped storage power, regarding the wind power, solar power, hydro power and pumped storage power as an entire complementary generation system.Considering multiple power constraints, there proposes two optimal scheduling models with the minimum volatility of the complementary system and the minimum volatility of the thermal power unit equivalent load. Then we use the beetle antennae search algorithm to solve the two models. Simulation results indicate that the two optimal scheduling models can track the optimization objectives well and reduce the impact of wind and solar power's connection to the power grid.
