Solar-gas-storage multi-energy complementary combined cooling heating and power system

Abstract

The invention provides a solar-gas-storage multi-energy complementary combined cooling heating and power system comprising a solar-storage microgrid subsystem, a gas combined cooling heating and powersubsystem and an energy management system. The solar-storage microgrid subsystem and the gas combined cooling heating and power subsystem are interconnected through a parallel contactor. The energy management system monitors and dispatches all the equipment in the solar-gas-storage multi-energy complementary combined cooling heating and power system. The capacity allocation principle is made forthe solar-storage microgrid subsystem and the gas combined cooling heating and power subsystem, and operation control is performed for the solar-gas-storage multi-energy complementary combined coolingheating and power system according to the winter and summer condition and the spring and autumn condition separately on the basis of the requirement for heating and cooling.

Description

technical field [0001] The invention relates to a combined cooling, heating and power supply system. Background technique [0002] With the rapid development of new energy in terms of technology and market, the complementary integration of different energy sources has become more and more widely used. The microgrid system emerging in recent years can realize free switching between grid-connected mode and off-grid mode. It is a typical application to ensure the reliability of power consumption in the system, improve the penetration of renewable energy, and be friendly to the grid. Generally, the power grid system can only meet the needs of users for electricity consumption, but not the demand for cooling and heating. At the same time, due to the high cost of batteries in the current energy storage system, a large number of energy storage systems will inevitably lead to huge investment in the micro-grid system. The relevant regulations of the National Energy Administration In...
