However, the volatility and unpredictability of new energy generation pose certain challenges to the accurate assessment of its effective capacity. Effective capacity is crucial to the safety and stability of the power system. It ensures that the system remains stable under various operating conditions and supports resource optimization, risk management, market operation and emergency response. Accurately assessing effective capacity helps power system planning, design, operation and regulatory compliance, ensures the reliability of power supply and the long-term security of the power grid. Existing technologies are currently in the initial exploration stage for the calculation methods of effective capacity of new energy and the calculation of effective capacity of energy storage.
