Abstract:

Under the background of energy internet, the scale of renewable energy interconnection is increasing day by day. Due to the strong randomness of renewable energy generation power, the so-called "bilateral stochastic problems" appears in the operation of the power system, which affects the safety and stability. How to manage all kinds of renewable energy economically and effectively is one of the key technologies to realize the energy internet. In order to realize the overall optimization of microgrid operation, a multi-objective optimization model was established for microgrid including various distributed generators (DG) with the lowest comprehensive power generation cost and the best environmental benefits as the optimization objectives. The genetic algorithm is used to optimize the energy management. The simulation results of a microgrid with multiple DGs running on the grid show the effectiveness of the optimization model and algorithm.
