Abstract:

With the rapid growth of installed capacity of wind and photovoltaic power, wind farms and photovoltaic power stations equipped with energy storage have the conditions to be black-start power supply. Using PV-wind-battery system as black-start power supply can improve the black-start capacity of regional power grid. Therefore, this paper designs a feasible evaluation method for the PV-wind-battery system to be black-start power supply. First of all, the output power of the PV-wind-battery system is analyzed from the perspective of load demand of black start, and the support probability and existing problems of black start with PV-wind-battery system are obtained. Then, on the basis of the power prediction method and power evaluation index, the feasibility evaluation method for the PV-wind-battery system to be black-start power supply is designed. The reference value of output power of PV-wind-battery system is obtained by the power prediction method. The feasibility of the PV-wind-battery system to be black-start power supply is determined by the evaluation index of output power of PV-wind-battery system. Finally, using MATLAB simulation software, different scenarios are designed to verify the effectiveness of the feasibility evaluation. The results show that the output power of wind-solar-storage power generation system can meet the power requirements of black-start load when the execution probability inclination is greater than 1.

Key words: black start, photovoltaic-wind-battery system, feasibility evaluation, power prediction
