Abstract

A three-sided complementary distributed energy system and a three-sided complementary distributed energy microgrid system are disclosed, comprises a fuel-side complementary subsystem, an electric energy-side complementary subsystem and a thermal energy-side complementary subsystem, wherein the fuel-side complementary subsystem comprises a complementary structure of biomass gas and natural gas forcomplementary utilization between the biomass gas and the natural gas; The power-side complementary subsystem comprises a complementary structure of an adjustable power supply and a non-adjustable power supply, which is used for complementary utilization between the adjustable power supply and the non-adjustable power supply to suppress random fluctuations. The thermal energy side complementary subsystem comprises a complementary structure of photothermal and device waste heat, which is used for complementary utilization between photothermal and device waste heat. The three-side complementarydistributed energy system and the micro-grid system consider the multi-source complementary utilization of the renewable energy from the fuel side, the heat side and the electric power side, so that the complementary characteristics of various energy forms on the fuel side, the heat side and the electric power side can be fully brought into play, and the energy utilization efficiency can be effectively improved.

Description

technical field [0001] This application relates to the technical field of energy utilization, in particular to a three-side complementary distributed energy system and a three-side complementary distributed energy micro-grid system. Background technique [0002] With the rapid development of science and technology, people consume more and more energy in their daily life. In order to increase the utilization rate of energy and reduce the environmental pollution caused by energy consumption, distributed energy systems have been developed rapidly. Distributed energy is a comprehensive energy utilization system built on the user side, which can realize grid-connected operation or independent operation. It has the advantages of reasonable energy efficiency, low loss, low pollution, and flexible operation. [0003] The traditional distributed energy system mainly considers multi-energy complementarity and thermal energy cascade utilization from the perspective of thermodynamics, a...
