Abstract
The UHVDC hydropower from southwest China and cascaded hydropower plants in received power grids constitute a new hydropower optimization of complex hydropower system crossing multiple provincial power grids. The typical Xiluodu-Zhejiang UHVDC engineering in China is taken as the background. An optimization method for hydropower system operations crossing provincial power grids is developed. The objective of maximizing minimum generation is considered in the model. The differences of river hydrology and storage volumes are used to determine the reasonable work position and running order of hydropower plants. The progressive optimality algorithm and dynamic programming successive approximation are integrated into a solution framework to optimize the power generation of hydropower plants. An interconnected hydropower system with UHVDC including Xiluodu Hydropower Plant and cascaded hydropower plants in the receiving power grid is presented. The simulation results show that our method can improve the overall firm generation. It is demonstrated that the coordination between hydropower plants located in different rivers and provinces is very important and necessary for efficiently transmitting large-scale hydropower in China.
