Abstract

The volatility of wind and photovoltaic power generation increases the difficulty of the grid to absorb renewable energy. To solve this problem, the demand side price response participation is introduced, and the hierarchical optimization method is used to study the distribution network configuration with distributed generation. At the planning level, the economic and network loss effects are considered to determine the demand side grid regulation load capacity and the installation location of distributed generation. Based on the planning scheme, the operation layer considers two modes: the controlled participation of the grid control load and the active participation of the price incentive load, and evaluates the economic operation, renewable energy utilization rate, voltage stability, and peak cut of different participation degree operation schemes. To improve the solution efficiency of the hierarchical optimization and maintain the diversity of the solution set, a particle swarm algorithm based on simulated annealing is used for calculation. Finally, the rationality and effectiveness of the proposed method are verified by the simulation analysis of an actual distribution system in Northeast China.
