Technical FAQs 4

How do energy storage systems compensate for PV power forecast errors?

Compensating for PV power forecast errors is an important function of energy storage systems [16, 17]. The capacity of an energy storage system is calculated based on the PV power forecast; an energy storage device is used to compensate for the power forecast error , effectively reducing the loss caused by the PV power forecast error.

Why is it important to compensate for photovoltaic (PV) power forecast errors?

Compensating for photovoltaic (PV) power forecast errors is an important function of energy storage systems. As PV power outputs have strong random fluctuations and uncertainty, it is difficult to satisfy the grid-connection requirements using fixed energy storage capacity configuration methods.

Why is energy storage important in a photovoltaic system?

When the electricity price is relatively high and the photovoltaic output does not meet the user’s load requirements, the energy storage releases the stored electricity to reduce the user’s electricity purchase costs.

Why is high capacity energy storage important for PV power generation?

PV power generation adversely affects the economic, safe, and reliable operation of power systems [3, 4]. High- capacity energy storage is a key technology in addressing the uncertainty of PV power generation that introduce fluctuations in the grid [5, 6].
