Can fixed energy storage capacity be configured based on uncertainty of PV power generation?
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. In this paper, a method of configuring energy storage capacity is proposed based on the uncertainty of PV power generation.
How much storage capacity should a new energy project have?
For instance, in Guangdong Province, new energy projects must configure energy storage with a capacity of at least 10% of the installed capacity, with a storage duration of 1 h . However, the selection of the appropriate storage capacity and commercial model is closely tied to the actual benefits of renewable energy power plants.
What is a configured energy storage system?
The configured energy storage system compensates for power differences and tracks the target output of the PV system. The required energy storage system capacity depends on the forecast error; the same configuration for all conditions is likely to increase energy storage system operating costs.
