Customer ServiceThe capacity of a battery or accumulator is the amount of energy stored according to specific temperature, charge and discharge current value and time of charge or discharge.
With battery installation to cope with the intermittent and fluctuating PV generation, the distributed photovoltaic battery (PVB) system is a typical prototype for distributed energy systems, and its design optimization is paid more attention to.
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.
We show that there is a unique critical value (denoted as E max c, refer to Problem 1) of the battery capacity (under fixed maximum charging and discharging rates) such that the cost of electricity purchase remains the same if the battery size is larger than or equal to E max c, and the cost is strictly larger otherwise.
The joint optimization of PV and battery sizes is presented by Li et al. under TOU for minimizing total annual system electricity cost. Moreover, the optimal PVB system operation is scheduled by Alramlawi et al. to address the grid blackouts with longer battery lifetimes via model predictive control (MPC).
The other limitations of the system device, socioeconomic conditions, and climate influence should also be concerned. The commonly used system limitation lies in the system power balance, battery charging/discharging rate limits, battery SOC upper and lower limits, and equipment lifetime especially considering the battery aging in Section 3.2.1.
