摘要：
To enhance power supply reliability of stand-alone photovoltaic (PV) generation system and improve PV utilization, it is necessary to configure the capacity of PV modules and energy storage devices reasonably. Based on the feature of joint-operation of PV generation system with energy storage device and considering dynamic variation of stored energy during the joint operation, taking technical characteristics of energy storage unit as the constraint a joint configuration method of PV capacity and energy storage capacity, in which the loss of power supply probability (LPSP) and energy excess percentage (EXC) are taken as assessment indices, is proposed. Under the conditions of a given case, taking three kinds of batteries, namely the valve regulated lead acid battery (VRLAB), the lithium-ion battery and all-vanadium redox flow battery, into account, the capacity of the three kinds of batteries are respectively configured and taking the minimized initial investment as the objective, the optimized capacity configuration of PV modules and energy storage units is computed. Computation results show that under the same configuration a higher power supply reliability can be achieved by use of all-vanadium redox flow battery, however under the condition of satisfying the requirement of indices, the initial investment can be the minimum while the VRLAB is adopted.
