Abstract:
With the increasing penetration rate of renewable energy generation and the rapid development of integrated energy system, an electric-thermal-hydrogen multi-energy storage (MES) optimized scheduling method is proposed. Firstly, the framework and equipment model of MES are established. On this basis, the influence of time-of-use pricing is taken into consideration, and a multi-objective optimal dispatch model of MES is proposed to achieve the unified effect of economy, efficiency and stationarity. The objectives of the model is to maximize the economic benefit, minimize energy loss and minimize power fluctuation between microgrid and external grid with participation of energy storage dispatching. Finally, a specific example is used to simulate and analyze the economic benefits of MES and the influence of energy loss and power fluctuation on economic benefits. The results show that the proposed model is scientific and effective.
