Abstract:Using demand response (DR) and improving the distributed energy resource (DER) are efficient ways to fulfill the requirement of the power generation and transmission construction. It is difficult for traditional distribution network to completely satisfy the DER access with high permeability. Meanwhile, the DR based on the price and incentive mechanism is lack of driving force under current policy and market environment. To solve the above problems, this paper takes the energy storage system of distribution network hierarchically, exerts the initiative of energy storage system through hierarchical decentralization and responsibility authorization, and energy storage with different hierarchies carries out demand response via autonomous coordinate control. The strategy can improve distributed generation permeability, delay the upgrading and rebuilding of the distribution network, increase the asset utilization, meet the requirement of the regional distribution network reliable operation, power quality, and power supply reliability, etc., and achieve the application of energy conservation in power system. The active power demand management system based on this research result has been applied in the national energy application technology study and engineering demonstration project, which proves the practicality and efficiency of the strategy.
