摘要：This paper focus on the coordination and optimization of renewable energy power generation capacity and other multiple energy sources in the power grid and the operational efficiency of renewable energy power generation equipment. The detail description of multi-energy system model composed of high proportion of wind power generation, photovoltaic power generation, solid regenerative electric boiler, electricity-generated natural gas, gas energy storage, and thermal energy storage system (ESS), renewable energy based on different scheduling time scales. First, the proposed power generation capacity planning and profit multi-objective optimization model. Second, investigate the energy supply and consumption characteristics of multi-energy supply, transmission, and load equipment in the power grid, and establish a multi_fenergy grid power balance model based on the uncertainty of high-ratio renewable energy generation. Finally, testing the proposed model using the actual operation data of a multienergy grid in a region of northeast Pakistan. The simulation results show that the renewable energy capacity and benefit optimization model can achieve a smaller renewable energy capacity allocation on the premise of ensuring higher investment benefits.
