Background:
With respect to the problem of wind power and photovoltaic (PV) grid-connected
accommodation, a power system optimization dispatching method is proposed that introduces a concentrating solar power
(CSP) station to promote wind power and PV accommodation, considering the dispatch-ability of the thermal storage
system (TSS) and the accommodation capacity of the electric heating device (EHD) in the CSP station.
Methods:
The method analyzes an internal simplified model of a CSP station and a short-time-scale identification method
of wind and PV power ramping events based on a CSP-Wind-PV system structure. Furthermore, the operating
characteristics and constraints of various units are considered with the goal of the lowest comprehensive system cost to
establish a CSP-Wind-PV optimization model for dispatching power system.
Results:
The method is simulated and verified on the IEEE-RTS24 node system by using the MATLAB optimization
toolbox.
Conclusion:
The results demonstrate that the participation of a CSP station can decrease the number of power ramping
events and reduce the curtailment of wind and PV power while ensuring the economical operation of the power system.
