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.
The connection of energy storage devices to the power grid can not only effectively utilize the power equipment, reduce the power supply cost, but also promote the application of new energy, improve the stability of the system operation, reduce the peak–valley difference of the power grid, and play an important role in the power system.
Power supply side methods can effectively improve the consumption of DGs and reduce the peak load regulation problem in power systems. However, the peak load and large peak-valley difference in distribution networks caused by the integration of high proportion DGs are not reduced in refs. [8, 9].
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.
In this paper, a comprehensive configuration strategy of energy storage allocation and line upgrading has been proposed. This strategy can reduce the peak load and peak-valley difference caused by the rapid development of loads and the integration of a high proportion of PVs in distribution networks.
