Sizing batteries for hybrid or grid-connected PV systems is beyond the scope of this recommended practice. Installation, maintenance, safety, testing procedures, and consideration of battery types other than lead-acid are beyond the scope of this recommended practice.
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.
This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This recommended practice does not include PV hybrid systems nor grid-connected systems. This recommended practice covers lead-acid batteries only; nickel-cadmium and other battery types are not included.
Considering the uncertainties of PV productions and electricity load, a two-stage stochastic MILP method was presented and the battery degradation was estimated by the annual decrease of 3.0% in battery capacity. Moreover, the optimization results of different tariff profiles and levels, feed-in tariffs (FiTs), and unit prices are studied.
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.
If the PV system is grid-connected, batteries can reduce the fluctuation of PV output or provide economic benefits such as demand charge reduction, capacity firming, and power arbitrage. The work in analyzes the relation between available battery capacity and output smoothing, and estimates the required battery capacity using simulations.
