Insights on Capacity Value of Photovoltaic Systems Coupled with Batteries

摘要: In the transition to a power system based on renewable energy sources, resource adequacy becomes an increasingly important topic. The capacity that distributed generation coupled with duration-limited electricity storage can supply during peak residual load hours, i.e. value, is still underexplored territory. this research, we investigate value ratio for community battery photovoltaic (PV) systems, using various optimization algorithms. We show batteries which are only charged PV-generated have mean of 50% when looking at 1.5 GW (peak ∼8%) Dutch system, whereas grid-charged 76%. Results robust analyses different years, but do exhibit large variations between days. Furthermore, amount considered has impact, as well discharge time battery.
