Abstract
This paper proposes a quantitative assessment method for renewable energy accommodation measures based on time-series simulations. Firstly, by analyzing principle and influencing factors of renewable energy accommodation, we establish a renewable energy accommodation assessment model that takes into account the delivered power and electrochemical energy storage using the time-series production simulation method. Then a segmented optimization algorithm is developed to solve this model. Further, based on the model we present a quantitative assessment method for enhancing the accommodation capacity of renewable energy. Moreover, a method for evaluating the contribution of each measure is obtained according to these quantitative assessment results. Finally, a calculation example based on a provincial power grid in Northeast China is presented to verify the rationality and effectiveness of the proposed method, which provides a theoretical basis for formulating renewable energy accommodation measures.
