Research on Equipment Scheduling Method for New Energy Access to AC/DC Hybrid Microgrids
To solve the problem of poor equipment scheduling of the existing alternating current/direct current(AC/DC)hybrid microgrid,the equipment scheduling method for new energy access to AC/DC hybrid microgrids is proposed.Firstly,the uncertainty factors of AC/DC hybrid microgrid in the operation process are analyzed.Then,the objective function of optimal scheduling of microgrid is established with the goal of improving the stability of grid operation;at the same time,the optimal scheduling model is constructed through the equation constraints on the power balance of the AC/DC side and the inequality constraints on the distributed power source and the storage battery.Finally,the optimal fireworks algorithm is used to solve the scheduling model,which ensures the stability of the model and also realizes the optimal scheduling of the AC/DC microgrid equipment.The experimental results show that by applying the proposed method,the microgrid is in the state of selling electricity for a long time,and the scheduling cost is always within CNY15.The method can improve the stability and economy of microgrid operation.
