Abstract

As the penetration rate of wind and solar power in network rises, it is more difficult for power grid to absorb new energy of the distributed generation. To solve this problem, a demand-side resource response model is stabished. Staged optimization method is used to study coordinated regulation of power grids with distributed generation. In the first stage, the grid-connected position of distributed generation and pumped storage is optimized by the sensitivity of network loss. In the second stage, the controlled resource capacity is determined according to the economic cost. On this basis, different scenarios are divided with the response capacity in the third stage. Considering the synergy of active and passive resources, the effects of different optimal cases on economic operation, new energy utilization, voltage stability and peak cut of power grid are analyzed. In order to enhance the solution efficiency of staged optimization and the diversity of solution sets, an improved particle swarm algorithm is used. Finally, simulation analysis of a practical power grid in Northeast China validates the correctness and effectiveness of this method.
