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.

System Controller

The Hybrid Fuel Cell Bus investigated adopts a hierarchy control system structure, of which the four main components have independent sub-controllers, and besides, a super-level Vehicle System Controller (VSC) was added to coordinate the system operation. The vehicle has dual power sources, fuel cell engine and battery, which implies that for a certain power demand of the driver, power distribution between them should be determined. This brings the possibility of system optimization while requires well coordination of the distributed sub-controllers in a system-level coherent way, which to some extent increases the complexity of controller design. Based on the experimental modeling of the fuel cell bus, this paper presents a systematic design method of the VSC supervisory control strategy to address these issues. For the validation of the developed VSC, a hardware-in-loop (HIL) simulation platform was setup. From the virtual tests, controller functions validation and parameters precalibration were achieved. Finally, the VSC was tested on the test bench and successfully applied to the target Hybrid Fuel Cell Bus. Experimental testing results show the satisfactory performances of the developed VSC.

According to the phenomena of regular grooves on the face of seal gasket which causes the hundreds of gaskets irrational failure in the valves of pressure-swing absorption (PSA) for CO refinement in a cathay coal chemical CO.LTD, the method of computational fluid dynamics (CFD) has been used to analyze the fluid dynamical performances of the mixed gas flowing in the pipe system of the PSA to study the reasons of the irrational failure of the seal gasket. Conclusions have been obtained as following: the main reason of Teflon seal local inactivation is the irrational seal system structure which causes the local high-velocity over the face; a rational modified scheme has been offered; the method which can be used to analyze similar problem has been explored in this paper.
