View moreThe participation of energy storage equipment in peak shaving can reduce system costs in terms of the peak shaving cost, abandoned wind and photovoltaic penalty cost and the total system power generation cost.
At the same time, this paper explores the mechanism of energy storage assisting the thermal power unit peak shifting to build an economic decision-making model and its optimal operation strategy that includes the factors of energy storage life loss and the cost of peak shifting of the thermal power unit.
The output power of thermal power units in Scenario 1 and Scenario 2 is shown in Figure 3 A,B, respectively. It is observed that the participation of energy storage in peak shaving can reduce the demand for deep peak shaving during low-load periods in the early morning.
The conventional thermal power unit has proven inadequate for meeting the demands of large-scale wind and solar grid integration. To address this issue, the combination of energy storage and deep peaking operation in thermal power units has emerged as a promising approach to enhance the peaking capacity of the system .
