Abstract

The invention relates to a method for configuring energy storage capacity in a photovoltaic / energy storage integrated system, and its technical features include the following steps: Step 1. Taking a photovoltaic / energy storage system project in a certain place as a reference, establish a storage system including a lead-acid battery. energy storage system and lead-carbon battery energy storage system integrated photovoltaic / storage system; step 2, formulate appropriate energy management strategies to control the power flow of lead-acid battery energy storage system and lead-carbon battery energy storage system respectively; step 3, Establish a lead-acid battery energy storage system and a lead-carbon battery energy storage system that are respectively used to cut peaks and fill valleys and suppress fluctuations, and design and calculate the energy storage capacity under different functional conditions; After filling the valley and suppressing the capacity of the energy storage system during fluctuations, a corresponding simulation model is built for simulation. The invention combines the lead-acid battery and the lead-carbon battery as an energy storage system, and uses a suitable energy management strategy to control the energy storage system to cut peaks and fill valleys and suppress fluctuations.

Description

technical field

[0001] The invention belongs to the technical field of new energy management, and relates to a method for configuring energy storage capacity, in particular to a method for configuring energy storage capacity in a photovoltaic / energy storage integrated system. Background technique

[0002] After the 1970s, with the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent. Traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At the same time, about 2 billion people in the world do not have access to normal energy supply. At this time, solar energy has become the focus of attention due to its unique advantages. Abundant solar radiant energy is an important energy source, inexhaustible, non-polluting, cheap, and freely usable by human beings. Its potential for development and utilization is very broad. However, as photovoltaic power g...
