The invention discloses a distributed power source multi-point dynamic connecting-in optimization distribution method. According to the distributed power source multi-point dynamic connecting-in optimization distribution method, grid connecting nodes are dynamically selected, network loss influences on a power grid generated after each grid connecting node is connected to a distributed power source are calculated, data classification is carried out on the grid connecting nodes according to the network loss of the power grid, distributed power source nodes are clustered and ranked according to the network loss influences on the power grid, the energy injection rate of the power connecting distributed power source nodes is distributed, and the distributed energy injection rate of the distributed power source serves as the initialization condition, the energy injection rate of the distributed grid connecting power source is optimized through a particle swarm optimization, and the purpose of minimizing the network loss of the power grid is realized. The distributed power source multi-point dynamic connecting-in optimization distribution method minimizes the network loss of the power grid, is flexible to use, can dynamically adjust the connecting-in and energy injection rate of the distributed power source, effectively improves the generation efficiency of the distributed power source, guarantees fairness, and reduces the network loss of the power grid.
Description
technical field [0001] The invention belongs to the technical field of new energy control, and relates to an optimal distribution method for multi-point dynamic access of distributed power sources. Background technique [0002] The rapid development of the economy has promoted the rapid growth of electricity demand, but the disadvantages of the reliability and stability of the traditional centralized power generation and long-distance transmission power system are becoming more and more obvious. At the same time, the energy crisis and the pressure of environmental protection are gradually increasing. The rapid consumption of fossil fuels and the pollution caused by combustion applications have also seriously affected people's normal life. Therefore, the application of green and clean new energy and renewable energy has received more and more attention. Distributed power generation converts scattered clean energy into electrical energy, making the most effective use of distr...
