Microgrid plays an important role in absorbing rural distributed renewable energy and ensuring the reliability of power supply. In order to reduce the waste of clean energy and improve the operation efficiency of microgrid, a cooperative game-based optimization method for microgrid and distribution network is proposed. Firstly, combined with the complementarity of wind power, solar power and biogas power generation in time, the cooperative operation mechanism of micro power is established. Load characteristics are taken as constraints and the minimum operating cost as objective function. Then, a microgrid alliance protocol based on cooperative game theory is proposed, in order to maximize the benefits of microgrids. In the alliance, power surplus microgrid sells electric to power shortage microgrid to realize complementary power supply. So as to improve the distribution efficiency and reduce the overall operation cost. Finally, it proposes a complementary power supply scheme between microgrid alliance and distribution network as well as a revenue distribution method. For the distribution of benefits, Shapley value method is discussed in order to distribute benefits fairly. On the basis of theoretical research, the objective function and constraint conditions are designed to build the algorithm model and write program for simulation. The analysis results show that cooperative game optimization operation of microgrid and distribution network can effectively improve the distribution efficiency and increase benefits. |
