Swedish chemical solar container peak-shaving power station

What is peak shaving function in Solax inverter?

With Peak shaving function, SolaX inverter will be your smart home energy manager to control the overall usage of energy in the house and maximize energy self-consumption in a smarter way. This period allow inverter to take energy from grid to charge battery in order to have enough backup for peak shaving.

How does peak shaving work?

The extra costs in keeping up with the peak demand are passed to the customers in form of a power fee, i.e. you pay for your maximum peak load. By utilizing Peak shaving, peak load can be reduced and hence the power fee. System is controlled to charge up during off-peak hours and discharged during peak hours.

What is es peaking power correction?

4.2.1. Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.

Why is peak shaving unbalanced?

Due to the cost of deep peaking of conventional units, the system needs a larger charging power provided by ES to participate in peak shaving when the power of RE is larger (e.g. Fig. 7 (Typical day 3 0:00 to 8:00 p.m.)). In this way, the charge and discharge of ES involved in peak shaving may be unbalanced.

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.
