Coordinated Optimization Strategy for Grid-connected Microgrid Considering Demand Response
摘要
Abstract
To improve the economic benefit of microgrid,a coordinated optimization strategy for grid-connected mi-crogrid is put forward considering demand response(DR). First,a model of controllable load(CL)and a model of gen-eration units of microgrid are established. Then,a bi-level coordinated optimization model for microgrid is established. On the upper level,the CL on the user side can be guided by the time-of-use(TOU)electricity price to participate in the DR on the basis of satisfying the user's comfort degree,and the optimized load curve is output to the lower model;on the lower level,the output power of distributed sources,discharging/charging power of battery energy storage system (BESS),and grid-connected power are optimized on the basis of meeting the supply-demand balance and the con-straints of generation units to reduce the daily operation cost of microgrid. Finally,differential evolution(DE)algorithm is employed to solve the bi-level coordinated optimization model,and simulation results of an example in different modes verify the validity of the proposed strategy.关键词
