Optimized Configuration of Energy Storage in Distribution Network Considering Uncertainty and Demand Response
摘要
Abstract
The intermittency and uncertainty of distributed power sources make the large-scale access a challenge to the safe and stable operation of the distribution network,and the reasonable configuration of energy storage systems in the distribution network can effec-tively deal with this problem.Therefore,in order to reduce the adverse effects of wind and solar integration and improve the power quality of the distribution network,firstly,it constructs a distribution network model which is jointly accessed by distributed power sources and energy storage systems.Secondly,the output uncertainty of renewable energy is processed and the demand response model is constructed to smooth the load curve.Then it constructs a multi-objective optimization model of energy storage in the distribution network with the lowest annual comprehensive cost and the smallest voltage deviation as the optimization objectives.Finally,taking the IEEE 33-node distribution network as an example,the energy storage access location is determined according to the node voltage devia-tion caused by distributed power access,and the optimized configuration scheme of energy storage is determined by improved particle swarm algorithm.Simulation results show that the proposed model can improve the system economy and stability,while the improved particle swarm algorithm is better in solving effect.关键词
