Multi-energy complementary system universal operation method

Abstract

The present invention provides a multi-energy complementary system universal operation method. The multi-energy complementary system comprises two major categories consisting of a cooling, heating andpower coupling multi-energy complementary system and a cooling, heating and power decoupling multi-energy complementary system. The cooling, heating and power coupling multi-energy complementary system comprises a combined supply system and any combination of a cooling output independent subsystem, a heating output independent subsystem and a power output independent subsystem; and in the cooling, heating and power decoupling multi-energy complementary system, outputs of cooling, heating and power are respectively achieved by means of combination of different independent subsystems. The outputs of the cooling, heating and power of the cooling, heating and power coupling multi-energy complementary system have coupling, an operation strategy comprises two modes consisting of ordering powerby heat and ordering heat by power; and each mode is determined according to determination of whether users have heating or cooling demands or not which are different in application occasions, and itis considered whether a power grid is in a normal access condition or not in each application occasion. The cooling, heating and power decoupling multi-energy complementary system basically has no coupling between each subsystem, and control of each subsystem is relatively independent; and moreover, the operation strategy is employed according to determination of whether users have heating or cooling demands or not which are different in application occasions, and it is considered whether a power grid is in a normal access condition or not.

Description

technical field [0001] The invention relates to an operation method of a multi-energy complementary system. Background technique [0002] Renewable energy includes water energy, biomass energy, wind energy, solar energy, geothermal energy and ocean energy, etc., with great resource potential, low environmental pollution, and sustainable use. It is an important energy that is conducive to the harmonious development of man and nature. In addition, natural gas, as a clean energy source, is also widely used in regional distributed energy systems. In response to the current demand for various energy sources for cooling, heating, electricity, and gas, a multi-energy complementary system has emerged as the times require. The multi-energy complementary system is to use the above energy sources to complement each other and comprehensively utilize them, so as to improve energy output and utilization efficiency, and meet users' energy demand for cooling, heating, electricity, and gas....
