Abstract

Abstract: Due to its various power sources, flexible operation modes and ability of making full use of distributed energy resources, microgrid has received broad attention. Focusing on the two different network modes of photovoltaic-battery system (PVBS), the power flow distribution of photovoltaic-battery hybrid system (PVBHS) and photovoltaic-battery integrated system (PVBIS) under different operation conditions are analyzed separately and the corresponding operational economy calculation model is proposed. Using the life cycle cost (LCC) analysis method, the economy of PVBHS and PVBIS is compared. A 6-bus microgrid lab system and the IEEE 33-bus test system are taken as the study case. Results show that the economy of the two network modes are various under different system conditions. The results can give evidence for choosing the optimal network mode.

Key words: photovoltaic-battery system, microgrid, network mode, economy
