A Novel Method for Configuring Concentrated Solar Power and Battery Energy Storage System with Consi -deration of Frequency Support Capability

An optimal configuration model for heat storage ca pacity and battery energy storage capacity is proposed in this pa per, based on economic benefits, inertial support capacity, and pr imary frequency modulation capacity. This model combines shor t-term, medium-term, and long-term system requirements while f ully considering uncertainties associated with wind and solar pow er generation. Its objective is to strike an optimal balance betwee <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$n$</tex> economy and performance. Through analysis of actual data, it i s evident that determining a reasonable heat storage time is cruci al for minimizing total control system costs. Furthermore, concen trated solar power stations can replace traditional thermal power generation without compromising the system's frequency suppor t capability; achieving 100% penetration rate of new energy sour ces is possible through this substitution approach. Increasing inst alled capacity in concentrated solar power stations helps enhance the system's frequency support capability but also leads to highe r comprehensive system costs.
