Who earns money from wind solar and energy storage peak load regulation

What is the difference between wind power and peak regulation?

Wind power is intermittent, random and has the character of anti-peak regulation, while the rapid growth of wind power and other renewable energy lead to the increasing pressure of peak regulation of power grid [1, 2, 3].

How energy storage system works in a wind farm?

The energy storage system acts as an auxiliary peak shaving source supply and coordinates with the thermal power unit to assist peak shaving. When the output of thermal power unit is less than the minimum output allowed by thermal power unit, the energy storage system is charged to absorb the output of wind farm.

Is abandoning wind power more economical than energy storage?

In WSST Project, the average charge-discharge cost of LiB is about 1.5 yuan/kW·h each time which is higher than the peak power price. Therefore, abandoning wind power is more economical than equipping with energy storage system. In fact, energy storage is now still at the stage of demonstration, the earnings are little . 3.2.

Do thermal power units participate in peak regulation auxiliary services?

Owing to China’s energy structure, thermal power accounts for nearly half of the country’s installed power generation capacity. Although the willingness of thermal power units to participate in peak regulation auxiliary services is low, we propose a peak regulation cost compensation and capacity-proportional allocation mechanism.

What is the difference between photovoltaic peak regulation and wind power profit?

The wind power profit and photovoltaic peak regulation are composed of the profit from electricity sales, the allocation cost, and the penalty for abandoning wind and light. The thermal power peak regulation profit is composed of compensation, allocation, and DPR costs. These are shown in Eqs. 7 – 9.

Why do thermal power plants have a lower reserve capacity?

The lower reserve capacity of thermal power plants is used to provide peak regulation power generation rights for renewable energy sources such as wind and solar energy. The load side adopts demand response (DR) to optimize the load curve.
