The method is characterized by comprising the steps: establishing a complementary mechanism of multi-energy complementary coordinated power generation in a multi-energy power system; constructing a mathematical model of a complementary index system and a complementary demand based on the complementary mechanism; defining a renewable energy complementary power supply; calculating the required matched water and electricity capacity ratio in the renewableenergy complementary power supply with the minimum complementarity demand as the target; formulating a hierarchical optimization operation strategy of the multi-heterogeneous energy power supply according to the complementarity index; solving the optimization objective function corresponding to each optimization layer by using a particle swarm algorithm, and calculating the output power value of the multi-heterogeneous energy power supply capable of enabling the complementarity index to reach the optimum at each time period. The method is scientific, reasonable, simple and practical, and is capable of improving the renewable energy consumption level.

Description

Technical field [0001] The invention relates to the field of optimized operation of electric power systems, and is an optimized operation method of a multi-energy electric power system based on the analysis of power supply complementary characteristics. Background technique [0002] With the outbreak of the energy crisis and the emergence of environmental pollution, the development and utilization of renewable energy has received unprecedented attention. However, due to the intermittent and fluctuating characteristics of wind power photovoltaic output power, it brings certain challenges to the optimization of the grid operation , Through the complementary characteristics of heterogeneous power sources, the impact of wind power and photovoltaic grid connection can be reduced, which plays an important role in reducing environmental pollution, improving energy utilization, and ensuring the stable operation of the power system. Therefore, using the space-time complementarity between ...
