Abstract:

In view of the uncertainty of wind and photovoltaic outputs in multi-energy coordinated optimal operation system under electricity market environment, a robust optimal scheduling model of wind-PV-storage multi-energy cooperative game considering fairness is proposed. Firstly, a multi-energy power system integrated with wind power generators, photovoltaic power generators, pumped storage power stations and photovoltaic thermal power stations (CSPs) is constructed, then a cooperative game optimization scheduling model considering fairness for this power system is established. On the basis of the cooperative game model and robust optimization theory, the model gets robust by introducing robust factors to transform the uncertain constraints into deterministic constraints. The model is analyzed and verified by a power grid in Gansu Province. The analysis shows that the model is flexible and can meet the operation requirements under different stability requirements. The system operator can adjust the inclusiveness of the randomness of the system by adjusting the robust coefficient. Compared with the benefit under non-cooperative game scenario, the overall benefit of the system adopting cooperative game is higher, since giving full play to the advantages of cooperative game can promote the reliable operation of new energy integrated system.
