Energy storage mitigates renewable energy curtailment by absorbing excess electricity generated during periods of high renewable output and low demand or grid constraints, then releasing it when demand is higher or grid capacity is available. . As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment. . curtailment is emerging as a common challenge facing a growing number of power systems. At its core, curtailment is a symptom of an insuficiently flexible power system. This reduces the need to limit renewable generation. .

This text explores how Battery Energy Storage Systems (BESS) and Virtual Power Plants (VPP) are transforming frequency regulation through fast response capabilities, advanced control strategies, and new revenue opportunities for asset owners. . Due to the fast response characteristics of battery storage, many renewable energy power stations equip battery storage to participate in auxiliary frequency regulation services of the grid, especially primary frequency regulation (PFR). Modern energy systems require increasingly sophisticated. . Frequency regulation is crucial for maintaining stability and efficiency in energy systems. It involves balancing electricity supply and demand to ensure that the frequency of alternating current (AC) remains within a specified range—typically 50 or 60 Hz, depending on the region. This is essential. .
