Multi-point layout planning method for multi-energy power system based on complex adaptive system theory

Abstract

Aiming at the problem of multi-point layout planning of multi-energy power system, the output characteristics of multi-energy power system composed of wind power generation, photovoltaic power generation, hydropower generation, traditional thermal power generation and solar thermal power generation are comprehensively analyzed. Combining power optimization planning with complex adaptive system theory, a multi-point layout planning model of multi-energy sources based on complex adaptive system theory is proposed. The model takes the minimum construction step size of each new energy source as the agent. Through the interaction between the agents and the accumulation of experience, the behavior rules are constantly changed, the installed positions of various types of power sources are adjusted, and the optimal layout scheme of various power capacities of each node is obtained. Moreover, an agent modeling method based on simple rules emerging complex phenomena is proposed, which reveals the core idea of complex adaptive system theory—adaptability makes complexity. Taking an actual power grid in a certain region of China as an example, it is verified that the proposed method has significant effect on improving the consumption of new energy, and has certain guiding significance for the actual engineering construction.
