Abstract:

Continuous optimization of source, grid and load factors is needed to solve the renewable energy curtailment problem. This article focuse d on the decomposition algorithm of contribution to renewable energy accommodation under the combined effect of source-grid-load. From the point of view of the planning, development scenarios were established under different source-grid-load factors, based on production simulation. Source-grid-load contributions to renewable energy accommodation were calculated by sensitivity analysis method and Shapley value method, respectively. The sensitivity analysis calculate contribution by judgment factors according to a specific scenario. It is suitable to give a list of measures for an established stage of development. The Shapley value method is a comprehensive weighting for the contribution of all development scenarios. It is more suitable for examining the whole process of development from the present situation to the level of planning.

Key words: production simulation, renewable energy accommodation, contribution rate, Shapley value method
