Abstract

Solar power availability is intermittent and must be accompanied by an energy storage system (ESS). Hence, a strategy is needed to combine the use of grid power, solar power, and ESS power to minimize the total cost of energy. A solution to this problem is proposed here as Advanced Optimal Resource Allocation (AORA). This control scheme uses the prediction of solar power availability, the real-time price of energy, and levelized costs of energy for both solar power and ESS to optimally combine the use of the power sources. Simulation results are presented for a 24 h prediction window and compared with a baseline power usage scheme that is based on a fixed charging and discharging schedule for the ESS. The comparison shows that AORA results in a substantial cost savings over the baseline scheme.
