A compound control method for optimal configuration of wind/PV/storage system

摘要

In the renewable energy system, aiming at the instability and strong randomness of wind and solar energy output power, a compound control method based on the energy storage ratio and the power smoothing parameters is proposed. The method can control the fluctuation amplitude within the set value by charging, discharging or running off the system. By simulating the two configurations of single and double energy storage, the compound control algorithm is used to carry out the simulation experiment, and the power smoothing effect, economic benefit and other comprehensive indexes are compared. The simulation results show that the system has better running effect under single energy storage.
