Abstract

The invention relates to a multi-energy complementary microgrid system which comprises an electric bus, a cooling bus, power generation equipment, refrigeration equipment and energy storage equipment.And the electric bus is connected with an external power grid. The power generation equipment is connected with the electric bus. And the refrigeration equipment is connected with the electric bus and the cooling bus respectively. The power generation equipment supplies electric energy to the refrigeration equipment. And the energy storage equipment is respectively connected with the electric busand the cooling bus. The power generation equipment supplies power to the energy storage equipment. The system has the advantages of being high in energy gradient utilization efficiency, reliable inelectric energy supply, good in economic benefit, environmentally friendly and the like. Power generation equipment, refrigeration equipment, energy storage equipment and the like are combined, and anexternal power grid is accessed in a micro-grid form, internal load fluctuation can be effectively adjusted, the electrical load in the peak period of a power grid is reduced, and the increasingly increased contradiction between peak and valley loads of a power system is relieved. The problem that the annual effective utilization time of power equipment is continuously shortened is solved, the electrical safety and the stability of the power grid are improved, and the power generation efficiency and economic benefits are powerfully guaranteed.

Description

technical field [0001] This application relates to the field of energy technology, in particular to a multi-energy complementary micro-grid system. Background technique [0002] During the development of Shenzhen’s power grid to the international advanced level, various problems such as increasing urban electricity demand, uneven distribution of power supply, large peak-valley load difference in summer, and low resource utilization efficiency have been exposed. With the development of Shenzhen's economy, the existing power grid structure will not be able to meet the needs of users well. While upgrading the existing power grid is urgently needed, the development of multi-energy complementary energy supply technology has become an inevitable solution to the energy supply of buildings in Shenzhen. need. [0003] The construction and operation of the multi-energy complementary micro-grid demonstration project will be of great significance to the commercialization and promotion ...
