During peak PV generation, excess energy can be stored for later use. This allows for the distribution of this energy when the PV system is not generating adequate power, or not generating at all. Energy storage is also used for peak smoothing with renewable generation.
Peak-load shifting in PV systems is achieved by efficiently controlling converters A and B, as illustrated in Fig. 5. Converter B, like A, employs a current closed-loop control with PI regulation to match battery current with the reference value, enabling peak-load shifting. Specific control details are not provided for brevity.
Peak shifting is a concept that can help address the issue of high energy demand during peak hours with a different approach: generation shifting. This means that Energy Storage Systems (ESS) not only help end users reduce their costs, but also enable generators to access a higher value of dispatchable generation.
As PV power grows to represent increased contribution to the grid, reliability issues could emerge, similar to the impact of wind power in states where wind has had much greater penetration\. The concept of peak shifting can help remedy this situation with a slightly different approach: generation shifting can help improve the reliability of PV power.
To verify the effectiveness of the RCCE method in peak-load shifting of the PV system, condition 7 is selected as the experimental object. It is assumed that the value of power demand of load in the valley period is about 1500 W–1600 W, and the value in the peak period is about 4200 W–4300 W.
Peak-load shifting refers to the process of mitigating the effects of large energy load blocks during a period of time by advancing or delaying their effects\. This process aims to minimize generation capacity requirements by regulating load flow in the power supply system.
