The effect of PV siting on power system flexibility needs

摘要

Locations of photovoltaic (PV) systems affect the variability and uncertainty of their power generation, and as a result the amount of flexible resources needed to balance supply and demand. However, studies on the integration of renewable electricity into power systems focus on the total amount of renewable generation, and not their locations. This paper uses a hidden state, spatial-statistical model to simulate how locational arrangements and balancing policies affect the need for reserves load following and regulation in California's power system when including 12 GW of photovoltaic generators and 9.5 GW of wind.
