This work assesses the economic feasibility of replacing conventional peak power plants, such as Diesel Generator Sets (DGS), by using distributed battery energy storage systems (BESS), to implement Energy Time Shift during peak hours for commercial consumers, whose energy prices vary as a function of energy time of use (ToU tariffs).
On this basis, an optimal energy storage allocation model in a thermal power plant is proposed, which aims to maximize the total economic profits obtained from peak regulation and renewable energy utilization in the system simultaneously, while considering the operational constraints of energy storage and generation units.
Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.
The dispatching department calls it for free. When the output of thermal power unit is between (1 − k) Pthe and 0.5 Pthe, the thermal power unit has the ability for peak shaving. At this time, there is no need to charge the energy storage system for peak shaving. To avoid deep discharge in energy storage system, SOCmin is set to 20%.
At present, the research on the participation of energy storage system in grid-assisted peak shaving service is also deepening gradually [4, 6, 7, 8, 9, 10]. The effectiveness of the proposed methodology is examined based on a real-world regional power system in northeast China and the obtained results verify the effectiveness of our approach.
