This paper examines the operation of the Irish power system with very high levels of wind energy, with and without pumped storage. A unit commitment model which accounts for the uncertainty in wind power is used. It is shown that as wind penetration increases, the optimal operation of storage depends on wind output as well as load. The main benefit from storage is shown to be a decrease in wind...

Compared with the traditional GIS station, complex wiring and operation mode of pumped-storage plant diversity, working condition frequent transformation, makes to produce very fast transient overvoltage (VFTO) probability increase greatly. VFTO will form a coupled shell casing earth voltage (TEV), then station personnel safety reliability secondary equipment poses great threat. But at moment b...

In this paper, the performance of constrained Generalized Predictive Control (CGPC) is investigated on a comprehensive non-linear multivariable simulation of the Dinorwig pumped-storage hydroelectric power station. The responses of the system are compared with those of the classic PI controller, as currently implemented on the plant. The results show that CGPC offers significantly better perfor...
