A2: Peak shaving energy storage involves storing excess energy during periods of low demand and using it during peak demand periods. This approach helps reduce the strain on the grid and can significantly lower energy costs. Battery storage is a popular method for energy storage in peak shaving. Q3: What are some common techniques for peak shaving?
Peak shaving can be accomplished by either switching off equipment or by utilizing energy storage such as on-site battery storage systems. The objective of peak shaving is to eliminate short-term spikes in demand and reduce overall cost associated with usage of electricity.
Two mechanisms respectively based on the unit load rate (ULR) and peak shaving contribution (PSC) are proposed and examined, and the bidding range and quotation range for peak shaving of CSP under the two mechanisms are suggested according to the cost of the peak shaving capacity of CSP.
Before the promulgation of these measures, peak shaving services were generally provided by thermal power units, gas-fired units, and hydropower. CSP plants could only passively accept superior dispatch, could not actively participate in the peak shaving AS market to obtain compensation, and had to share the compensation costs.
However, in strategy A, the participation of CSP in peak shaving increases the consumption of PV power and reduces the amount of curtailed PV generations by 6.67%. Meanwhile, the total dispatch cost of strategy A is less than that of strategy B, decreasing by 6.2%, because of the lower peak shaving costs of CSP and higher flexibility.
Current research on AS for peak shaving has primarily focused on hydropower units, thermal power plants, energy storage batteries, and demand response , , , , , , , . The research directions mainly concentrate on peak shaving trading mechanisms and peak shaving strategies , , , .
