A Method for Energy Storage Capacity Configuration of Integrated Energy Microgrid Considering Energy Storage Participation

Abstract

The invention relates to a method for configuring the energy storage capacity of an integrated energy microgrid considering the participation of energy storage, and its technical characteristics include the following steps: Step 1, inputting the electric heating load data of the integrated energy microgrid, the real-time electricity price of the integrated energy microgrid, Optimize the convergence judgment threshold and pollution treatment price; step 2, generate energy storage participation according to the real-time electricity price input in step 1; step 3, establish a comprehensive energy that considers energy storage participation, guarantees reliability, and aims at economy and environmental protection Optimal scheduling model; step 4, select n energy storage capacity values, and solve the comprehensive energy optimal scheduling model under different energy storage capacities; step 5, compare the index values ​​obtained by different energy storage capacities, select the optimal index value, and give The proposed value of the energy storage capacity configuration of the integrated energy system is obtained. The present invention considers the influence of real-time electricity price and peak-valley electricity price through energy storage participation, and effectively evaluates the ability of the energy storage system to participate in peak regulation.

Description

technical field [0001] The invention belongs to the technical field of energy storage capacity configuration of a comprehensive energy microgrid, and relates to a method for configuring the energy storage capacity of a comprehensive energy microgrid, in particular to a method for configuring the energy storage capacity of a comprehensive energy microgrid that considers energy storage participation. Background technique [0002] Energy is the "blood" of economic and social development. Since the beginning of the 21st century, both developing countries and developed countries have more or less been over-reliant on fossil energy, leading to domestic and foreign resource shortages, environmental pollution and other problems, and even affecting the global climate change trend, making people living environment is challenged. The integrated energy system integrates the production, distribution, transmission, transformation, storage and consumption of energy by integrating various ...
