Analysis of centralized photovoltaic energy storage configuration

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 determines the optimal configuration capacity of photovoltaic and energy storage?

The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.

What is the energy storage capacity of a photovoltaic system?

The photovoltaic installed capacity set in the figure is 2395kW. When the energy storage capacity is 1174kW h, the user’s annual expenditure is the smallest and the economic benefit is the best. Fig. 4. The impact of energy storage capacity on annual expenditures.

What is the main consumption mode and profit path for photovoltaic power stations?
