[1] Temperature and suspended particle distribution were surveyed and modeled in two high-Alpine reservoirs in Switzerland, connected by pumped-storage operations for 30 years. Due to different glacier coverage of the catchments, the two reservoirs exhibit different particle concentrations and temperatures. After ice-breakup, the lower reservoir with a higher glacier cover in its catchment expe...

The operation planning problem encounters several uncertainties in terms of the power system’s parameters such as load, operating reserve and wind power generation. The modeling of those uncertainties is an important issue in power system operation. The system operators can implement different approaches to manage these uncertainties such as stochastic and fuzzy methods. In this paper, new ...

In engineering construction, the accurate estimation of investment cost can provide a reasonable basis for formulation and decision-making construction scheme. this paper, wind-storage combined operation power station is taken as research object, model established, mode analysed to obtain annual generation. Finally, according generation, per unit electricity established. past, wind farm pumped ...

The unit commitment prob lem in a power generation system com prising thermal and pumped storage hy dro units is addressed A large scale mixed integer optimization model for unit commitment in a real power system is de veloped and solved by primal and dual ap proaches Both solution methods employ state of the art algorithms and software Results of test runs are reported

Pumped storage units bring stability to the electrical power system, so they must remain connected to the grid even during grid faults. In this paper, the authors propose efficient and simple solutions for a doubly fed induction machine pumped storage (DFIMPS) system during grid faults. In case of balanced grid faults, a control reconfiguration strategy is introduced and a hardware solution is ...
