In this paper, based on the basic principle of power system flexibility, the flexibility evaluation method framework of a WMCB system that considers wind-PV complementary characteristics is proposed to meet the needs of energy base development and planning.
Then, they obtained the optimal complementary power system consisting of wind power with the capacity of 2200 MW and PV power with the capacity of 1800 MW, the best capacity ratio of the wind-PV and hydropower was 1.1:1.
The complementarity evaluation index of the power system first increases and then decreases with an increasing PV capacity rate. When the wind power capacity rate is 43%, the complementarity evaluation index reaches the largest value, and the complementarity of the wind-PV reaches the best value.
Although the wind and PV power output processes are uncontrollable, the wind and PV power output of the power system is complementary to each other in terms of certainty and randomness. Therefore, the regional wind-PV power complementarity index considers fluctuation (CICF), is adopted in this study.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
