How to stabilize the impact of photovoltaic output uncertainty on peak shaving?

To stabilize the impact of photovoltaic output uncertainty on peak shaving, the scenario method is used to measure the uncertainty, and the stochastic optimization algorithm is used to solve the scheduling model, and the specific conclusions are as follows:

How does battery energy storage improve peak regulation?

Introducing battery energy storage for peak regulation reduces the pressure on thermal units, enhances system capacity, and lowers peak regulation costs . In deep peak shaving, battery storage follows the "high discharge, low charging" principle: charging during off-peak hours to increase load and discharging during peak hours to reduce load.

Does es capacity enhance peak shaving and frequency regulation capacity?

However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.

How effective is thermal storage peak regulation?

The effectiveness has been verified by the example of the proposed method. The enthusiasm of thermal storage peak regulation can be improved by the pricing strategy of thermal storage peak regulation, which can reduce the operating cost of the system to improve its operation flexibility.

What is the power and capacity of Es peaking demand?

Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.

Why should you use a PV system with a large storage system?

By using a PV system in conjunction with a large storage system and intelligent control, the connected load at the grid interconnection point can be reduced. Effective peak shaving stands and falls with the intelligent control of components in particular.
