abstract:
A strategy of compensating DC tie line inertia by differential control of energy storage was proposed in this paper. First, through the analysis of AC/DC transmission model and the inertia characteristics of DC tie line, a two zone AC/DC hybrid AGC system model considering inertia compensation was constructed. Then, energy storage output control was proposed to change the transmission power of DC tie line to form the inertia performance of tie line power change. On this basis, aiming at the negative effect of capacitance value on DC voltage in the process of energy storage extraction, the inertia compensation control strategy with superimposed energy storage differential was designed to improve the inertial response ability of the system. Finally, the feasibility and effectiveness of the proposed method were verified by comparing the simulation results of different load disturbance deviations and tie line overload rates.
