Research on Cooperative Optimization Control Strategy of Multitype Energy Sources

Abstract

With the increasing consumption of energy, the efficiency of energy utilization urgently needs to be further improved. At present, the coordinated optimization control of the integrated energy system of multiple types of cooling, heating, and power equipment is an important way to improve the comprehensive energy efficiency of the regional power grid and reduce the operating cost of the power grid. Aiming at this scenario, this paper establishes a fine energy storage model by analyzing the uncertainty of wind power output and considering the influence of low temperature and other conditions on the energy storage device in the energy storage side. On the load side, the influence of comprehensive demand response of electricity and heat on system operation is analyzed, and a combined cold, heat, and electricity supply system including renewable energy and energy storage device is established. Aiming at the optimal total cost of the integrated energy cooling and heating triple power system collaborative optimization control, the crow search algorithm is used to iteratively optimize the configuration model of the triple power system. The four models are considered in the article include groundless heat pump and energy storage, excluding joint demand response, including ground source heat pump and traditional energy storage model, excluding joint demand response, including ground source heat pump and fine energy storage model, excluding joint demand response, including ground source heat pump and fine energy storage model, taking into account the joint demand response. The simulation results show that the cooperative optimization control strategy of the combined cooling, heating, and power system with renewable energy and fine energy storage device model can enhance the system’s schedulable space, improve the comprehensive energy utilization efficiency, and have considerable economic benefits.

“…The cooperative game mode can improve the quality and safety level of fresh agricultural products, reduce the retail price of agricultural products, and expand the market demand of fresh agricultural products. Conclusion [4]; Zhang Xumei et al aimed at how to choose the appropriate subject to subsidize the fresh food supply chain, by establishing the Stackelberg game model of four situations: no government subsidies, subsidized suppliers, subsidized sellers, and subsidized consumers. Considering the impact of public welfare in an environment of uncertain demand, three conclusions have been drawn that the cooperative game model can improve the quality and safety of agricultural products, reduce the retail price of agricultural products, and expand the market demand for agricultural products [4].…”
