Energy storage provides an option to mitigate the impact of high PV penetration. Using the U.S. Eastern Interconnection (EI) and Texas Interconnection (ERCOT) power grid models, this paper investigates the capabilities of using energy storage to improve frequency response under high PV penetration.
This article qualitatively explores the process of photovoltaic power generation engaging in grid frequency regulation through establishing a LFC model of a power system incorporating photovoltaic power generation. The influence of different photovoltaic parameters on the system is revealed. The analysis results show that:
This strategy allows PV power generation systems with different reserve capacities to participate in frequency regulation, optimizing the load reduction controller and ensuring system frequency stability. However, this strategy cannot fully utilize the frequency modulation potential of photovoltaics with different capacities.
The frequency stability of power system with photovoltaic participation in frequency regulation is characterized by system frequency steady-state error, feedback system sensitivity, and closed-loop system stability margin.
