Large-scale construction of wind and PV power has become a key strategy for dealing with the energy crisis. However, the variability and uncertainty of large-scale renewable energy power stations pose a series of severe challenges to the power system, such as insufficient peak-shaving capacity and high curtailment rates.
Therefore, there is a need to focus on studying the approaches and benefits of new energy power stations (NEPSs) participating in the electricity market. NEPSs collectively refer to all large-scale renewable energy generation systems, including wind farms, solar power stations, and the mixture of them.
Energy storage complicates such a modeling approach. Improving the representation of the balance of the system can have major effects in capturing energy-storage costs and benefits. Given its physical characteristics and the range of services that it can provide, energy storage raises unique modeling challenges.
