Design method of intrinsically renewable energy complementary distributed energy system

Abstract

The invention discloses a design method of an intrinsically renewable energy complementary distributed energy system. The method comprises the steps of establishing a renewable energy complementary distributed energy system model, and finishing the production and supply of the cold, heat, electricity and gas loads of the users in a certain area range by fully utilizing the renewable clean energy,such as the light energy and wind energy in the nature, etc., through the wind and photovoltaic storage complementary power generation and in cooperation with the devices, such as a heat pump, a wasteheat boiler, an electrolytic cell, a hydrogen gas turbine, etc.; setting a multi-objective function according to the economic requirements and the system reliability indexes, namely the load power shortage rate and the output power fluctuation rate; and finally, obtaining an optimal solution of the objective function under a constraint condition by utilizing an elitist non-dominated sorting genetic algorithm NSGA-II, thereby obtaining the design parameters of the intrinsically renewable energy complementary distributed energy system, and obtaining an optimal combination scheme. According to the method, the internal energy structure is clear, the energy flow direction is clear, the energy can be effectively saved, and the system economy and energy supply reliability are guaranteed.

Description

technical field [0001] The invention relates to a design method of a distributed energy system. Background technique [0002] Since the 21st century, the supply of energy in the world has continued to be tight, and the rapid development of industry has caused a large amount of non-renewable fossil fuels to be consumed. In addition, the massive combustion of fossil fuels has also caused unpredictable harm to the environment. With the rapid development of my country's economy, environmental problems and energy pollution are becoming more and more serious, which have become the bottleneck restricting the sustainable development of my country's economy. It is imminent to actively adjust the energy structure, improve energy utilization, and solve environmental pollution problems. [0003] my country is rich in mineral resources, among which coal reserves rank first in the world, which determines the structural characteristics of coal-fired units and thermal power generation in my...
