With the integration of large-scale photovoltaic systems, many uncertainties have been brought to the grid. In order to reduce the impact of the photovoltaic system on the grid,
With the large-scale access of renewable energy, the randomness, fluctuation and intermittency of renewable energy have great influence on the stable operation of a power system. Energy storage is
Semantic Scholar extracted view of "Optimal capacity configuration of the wind-photovoltaic-storage hybrid power system based on gravity energy storage system" by H. Hou
The results show that, compared to the systems with a single pumped hydro storage or battery energy storage, the system with the hybrid energy storage reduces the total system cost by 0.33% and 0.88%,
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 abundant and idle roof resources in rural areas provide a good prerequisite for the promotion and construction of household photovoltaic (PV). Based on this background, this paper combs
This paper establishes a solid theoretical foundation for integrated photovoltaic and energy storage system configuration based on analysis. Firstly, a photovoltaic power station in a
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.
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.
The results show that the configuration of energy storage for household PV can significantly reduce PV grid-connected power, improve the local consumption of PV power, promote the safe and stable operation of the power grid, reduce carbon emissions, and achieve appreciable economic benefits.
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.
Yuan et al. proposed a PV and energy storage optimization configuration model based on the second-generation non-dominated sorting genetic algorithm. The results of the case analysis show that the optimized PV energy storage system can effectively improve the PV utilization rate and economy of the microgrid system.
