Abstract: In order to fully utilize the complementary characteristics between wind and solar power sources and reduce the fluctuations of renewable energy power generation, it is necessary to coordinately optimize the wind and solar power capacity proportion integrated in the multi-terminal voltage sourced converter high voltage direct current (VSC-HVDC) system. A method based on time sequence simulation is proposed to optimize the wind and solar power capacity proportion integrated in the multi-terminal VSC-HVDC system with a pumped storage power station. An optimization model is built aiming at maximizing the renewable energy power generation, which takes into account such constraint conditions as the operation modes of the VSC-HVDC system, the curtailment ratio of renewable energy, the system peak shaving demand and the operation limit of the pumped storage power stations. The annual outputs of the renewable energy are incorporated as inputs, the time sequence simulation is carried out to optimize the capacity proportion of wind and solar power. The proposed method is tested on a four-terminal VSC-HVDC system with a pumped storage power station. The testing results show that the proposed method can obtain the optimal wind and solar power capacity proportion integrated in the VSC-HVDC system, consequently realizing the objective of maximal utilization of renewable energy. The case study verifies the effectiveness and applicability of the proposed method, and can provide a useful guidance on planning renewable energy and the VSC-HVDC system.

Key words: multi-terminal VSC-HVDC, wind and solar power capacity proportion, time sequence simulation, pumped storage power station, mixed integer linear programming
