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 optimal capacity of rooftop PV was obtained as 9 kW for both configurations. The BESS capacity was optimally sized at 10 kWh for the PV-BESS system. It is shown that adding 9 kW PV in the PV only system decreased the total NPC to half of that of normal GCH without PV.
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.
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.
A framework is established for optimizing the scale and layout of rooftop photovoltaics. Energy storage and load shifting support significantly larger development scales. Scale and layout should be optimized to account for regional load differences. At least 90% grid flexibility 8–12 h of storage capacity are necessary in China.
The optimal capacities of rooftop PV and BESS were obtained as 9 kW and 6 kWh, respectively, for the PV-BESS configuration with TOU-Flat. It was found that changing the export power limitation would significantly change the COE and optimal capacity of PV, whereas it did not affect the BESS capacity.
