Comprehensive energy microgrid energy storage capacity allocation method by considering energy storage participation

Abstract

The invention relates to a comprehensive energy microgrid energy storage capacity allocation method by considering energy storage participation. The technical features thereof comprise the following steps of: the step 1, inputting electric heat load data, a real-time electricity price, an optimized convergence determination threshold and a pollution treatment price of an integrated energy microgrid; the step 2, according to the real-time electricity price input in the step 1, generating an energy storage participation degree; the step 3, establishing a comprehensive energy optimization scheduling model capable of considering the energy storage participation, ensuring the reliability and taking economic and environmental benefits as a target; the step 4, selecting n energy storage capacityvalues to solve the comprehensive energy optimization scheduling model in different energy storage capacities; and the step 5, comparing the index values obtained by different energy storage capacities to select an optimal index value and give a comprehensive energy system energy storage capacity configuration suggestive value. By employing the energy storage participation and considering the influences of the real-time electricity price and the peak and valley electric prices, the capacity of the energy storage system participate in peak shaving is effectively evaluated.

Description

technical field [0001] The invention belongs to the technical field of energy storage capacity configuration of an integrated energy microgrid, and relates to a method for configuring an energy storage capacity of an integrated energy microgrid, in particular a method for configuring an energy storage capacity of an integrated energy microgrid considering the degree of energy storage participation. Background technique [0002] Energy is the "blood" of economic and social development. Since the beginning of the 21st century, whether it is a developing country or a developed country, there are more or less problems due to excessive dependence on fossil energy, which leads to resource shortages at home and abroad, environmental pollution, and even affects the global climate change trend, making people living environment is challenged. Comprehensive energy system, through the integration of various energy sources including electricity, gas, cold, heat, etc., integrates the pro...

Problems solved by technology

However, most of the existing energy storage capacity configuration methods consider the consumption of distributed power sources and the balance of load supply and demand. Generally, the energy storage capacity is optimized with the goal of cost economy, lack of consideration of the participation of energy storage, and no economical, Energy storage capacity configuration optimization from multiple perspectives such as environmental protection and reliability
