Under the 100 % SOC limit, the battery capacity declines by 22 %–28 % annually, which is much higher than the limit of 80 % and 70 %. Meanwhile, the battery lifetime based on recommended capacity design can be improved further by 8.6 %, 4.0 % and 2.0 % with controlling the battery charge rate.
This is mainly because the power generated by PV plays an important role in electricity charged by the battery system for FiT 1, while the amount of electricity stored by the battery from the PV system is far less than that from the power grid for FiT 2. Therefore, PV degradation has a great impact on the optimal battery capacity for FiT 1.
Under the feed-in tariff profile of flat rate (FiT 1), the optimal battery capacity with battery degradation is 9.89% larger and the cost is 3.28% higher than that without battery degradation.
Solar photovoltaic (PV) energy generation is highly dependent on weather conditions and only applicable when the sun is shining during the daytime, leading to a mismatch between demand and supply. (1) In this regard, merging PVs with battery storage presents to be the straightforward route to counteract the intermittence of solar generation.
