FAQs 6

How does peak shaving affect a power plant?

Combustion efficiency may decrease during peak shaving, especially under low-load operation, which can lead to an increase in the overall coal consumption rate, significantly affecting the power plant's operational costs.

What is joint peak shaving mechanism of virtual energy storage and CCPP?

The joint peak shaving mechanism of virtual energy storage and CCPP is shown in Figure 2, which fully considers the adjustable characteristics of virtual energy storage to achieve elastic adjustments of the demand-side response, as well as the complementary characteristics of carbon capture power plants. Figure 2. Joint peak shaving strategy.

How to reduce peak shaving pressure of thermal power units?

During peak periods, the output of wind power is small. Lowering the demand for the two types of IDRs can play a role in peak shaving, which can alleviate the peak shaving pressure of thermal power units (conventional and carbon capture).

Can a two-stage dispatch model be used for joint peak shaving?

Based on these, this paper establishes a day-ahead and intraday two-stage dispatch model for the joint peak shaving of virtual energy storage and carbon capture power plants. Initially, it examines the working principles of carbon capture devices and their potential advantages in peak shaving.

How does HPD improve peak shaving flexibility in combined CHP plants?

Peak shaving flexibility in combined CHP plants is enhanced by HPD through the efficient separation of electrical and thermal energy. Deep peak shaving capacity is expanded by integrated energy storage, including CAES and molten salt thermal storage, by offering an external energy buffer.
