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
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.
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.
When the electricity price is relatively high and the photovoltaic output does not meet the user's load requirements, the energy storage releases the stored electricity to reduce the user's electricity purchase costs.
However, considering the economy, since the storage cost is higher than the power purchase cost in the trough period, when the photovoltaic power generation storage capacity is enough to offset the demand in the peak period, it will not continue to store energy and choose to abandon the PV.
The process of capacity allocation of solving optimization model using PSO According to the capacity configuration model in Section 2.2, Photovoltaic penetration and the energy storage configuration are nonlinear.
The optimal configuration of energy storage capacity is an important issue for large scale solar systems. a strategy for optimal allocation of energy storage is proposed in this paper. First various scenarios and their value of energy storage in PV applications are discussed. Then a double-layer decision architecture is proposed in this article.
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
