MODELING AND OPTIMIZATION OF MICRO GRID SUPPLY AND DEMAND SYSTEM FOR RENEWABLE THERMAL ENERGY

The economic benefit of microgrid is the key factor to realize environment-friendly power supply. With the wide application of new energy power generation, schol-ars have carried out a lot of research on microgrid models, but the existing mod-els cannot reflect the important role of renewable energy in microgrid operation. Therefore, the author proposes a power generation and storage model based on renewable heat energy and microgrid. In order to minimize the cost and meet the requirements of CO2 emission limitation, the cost of power generation, storage and production in the microgrid is analyzed in detail. At the same time, the optimization method of renewable energy microgrid system operation is also studied. First of all, by analyzing the characteristics of the microgrid system, a mathematical model and simulation calculation system are established to help understand the micro -grid system. Secondly, the author has carried out a separate study on the energy storage in the microgrid system, and listed the benefits and costs of the energy storage process. In the grid-connected state, the performance of each unit in the microgrid system is better, the system is more stable and safe, and the operating cost is reduced again..
