Basis for determining the energy storage capacity of photovoltaic modules

What is capacity configuration of energy storage for photovoltaic power generation?

Capacity Configuration of Energy Storage for Photovoltaic Power Generation Based on Dual-Objective Optimization Abstract. Capacity configuration is the key to the economy in a photovoltaic energy storage system. However, traditional energy storage con guration inaccurate capacity allocation results.

Why is energy storage important for PV power generation?

Energy storage for PV power generation can increase the economic bene fit of the active distribution network , mitigate the randomness and volatility of energy generation to improve power quality , and enhance the schedulability of power systems .

What is a bi-level optimization model for photovoltaic energy storage?

This paper considers the annual comprehensive cost of the user to install the photovoltaic energy storage system and the user’s daily electricity bill to establish a bi-level optimization model. The outer model optimizes the photovoltaic & energy storage capacity, and the inner model optimizes the operation strategy of the energy storage.

What is a decision variable in a photovoltaic system?

The outer objective function is the minimum annual comprehensive cost of the user, and the decision variable is the configuration capacity of photovoltaic and energy storage; the inner objective function is the minimum daily electricity purchase cost, and the decision variable is the charging and discharging strategy of energy storage.

What should be considered in the optimal configuration of energy storage?

The actual operating conditions and battery life should be considered in the optimal configuration of energy storage, so that the configuration scheme obtained is more realistic.

Does PV access affect the economic benefits of energy storage?

At present, there are many literatures on energy storage allocation. Paper and respectively use genetic algorithm and linear programming to solve capacity optimization, but they do not consider the impact of PV access on the economic bene ts of energy storage. In paper , a linear programming model for capacity and
