Multi-objective decomposition-coordination for mix-connected hydropower system load distribution

Abstract The multi-objective decomposition-coordination method for mix-connected hydropower system load distribution was proposed. Firstly, decomposition-coordination approach was applied to create link and compensation, and three-level structure of decomposition-coordination was adopted to decompose the optimal problem. Secondly, improved entropy approach was developed for calculating load compensation and allocation. According to results of simulative optimal operations premised on several representative hydrographs, joint optimal operation yields indications of superior performance.
