Medium- and long-term trading revenue model for peak-shaving energy storage projects

What is the business model of peak shaving?

generator with an investment in energy storage. Alternatively, the business model can be pursued a competitive tender if market regulation permits 30. The business model Peak shaving can be pursued by an investor in production, T&D, or consumption. While for the former two energy storage can by utilities for periodical demand peaks.

What is peak shaving in power system?

In the power system, the load usually shows “peak” and “valley” differences. It refers to the fact that the load is higher during certain times of the day and lower during other times of the day. In order to meet the peak demand, the power system needs to carry out peak-shaving.

What is peak shaving?

Peak-shaving refers to the reasonable adjustment of power system according to the change of power load to ensure the reliability and stability of a power supply. In the power system, the load usually shows “peak” and “valley” differences.

Will energy storage become the second largest peak-shaving resource?

By 2030, the scale of energy storage will expand rapidly, becoming the second largest peak-shaving resource in addition to thermal power units, as shown in Table 1. With the abundance of peak-shaving resources and the development of power auxiliary service market, the optimization of peak-shaving cost of power system has become an urgent problem.

Does energy storage affect peak-shaving cost?

On the other hand, references [35, 36] do not consider the impact of energy storage utilizing peak and off-peak electricity price arbitrage on the peak-shaving cost of the power system, thus failing to fully utilize the peak-shaving capabilities of energy storage.

What is the technical cost characteristic boundary of peak-shaving resources?

Thus, the technical cost characteristic boundary of various peak-shaving resources is determined. According to the typical daily renewable energy and load characteristics of Ningxia region, the quantification model of power system peak-shaving cost is established. The model takes into account the time-of-use electricity price factor.
