Current projects that have been authorized by the IEEE SA Standards Board to develop a standard. Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load.
Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load. The methodology includes testing the system outdoors in prevailing conditions and indoors under simulated conditions.
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.
Due to the uncertainty of building load and PV generation, the optimal configuration of PV and battery capacity are different under different PV and load scenarios.
Conclusions This paper presents a technical and economic model to support the design of a grid-connected photovoltaic (PV) system with battery energy storage (BES) system. The energy demand is supplied by both the PV–BES system and the grid, used as a back-up source.
According to the representative values, the configuration indices of PV and battery capacities for office buildings in the hot-summer and cold-winter climate zone, and the IV solar resource zone of China were explored, and summarized in the form of table. The summarized indices can be used directly as guide for PVB system design in practice.
