Peak shaving solar container auxiliary service

Does peak shaving reduce PV power consumption?

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.

Are CSP systems good for peak shaving?

While CSP systems are well suited for peak shaving, there are still some losses associated with participating in this process. However, compared with thermal power plants, CSP systems do not require boilers nor burn fossil fuels, so they do not have associated pollution costs.

Is peak shaving based on unit load rate & peak shaving contribution (PSC)?

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.

Should CSP-PV hybrid systems participate in peak shaving?

Over the life cycle of the CSP–PV hybrid system, participating in peak shaving AS could increase the comprehensive economic benefit by 3.80% and the curtailed PV power reduced by 2.50%.

Who provides peak shaving services?

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.

Should thermal power plants share peak shaving costs?

As a result, thermal power plants need to share peak shaving costs in the clearing process. The PSC-based mechanism is therefore suitable for power systems with a high number of CSP plants and other flexible peak shaving resources in the future.
