Abstract

To ensure the global of the non‑fossil energy proportion target, the renewable energy power absorptive safeguard mecha‑nism of China has been officially implemented. In this case, the reasonable formulation of weight indicators for absorptive responsibility is of great significance in guiding the healthy and orderly development of renewable energy. To effectively evaluate the current energy absorptive capacity of the system and provide support for the formulation of absorptive respon‑sibility weight indicators, a method for assessing the absorptive capacity of renewable energy power generation is proposed. This method constructs a system day‑ahead scheduling model that includes wind and photovoltaic power, comprehensively considers the constraints of secure operation of the power system and the impact of seasonal factors, and separately calcu‑lates the renewable energy absorptive capacity of the system during the transition season, summer, and winter. The calcula‑tion examples validate that the proposed method can determine the maximum renewable energy absorptive ratio of the power system in different seasons and use this to estimate the maximum annual renewable energy absorptive level of the system.
