The article presents simulation results of a developed model PSP Solina. was designed and executed in the Matlab – Simulink interface. A modular approach used to clearly distinguish characteristic elements model. Simulations performance were carried out for period 365 days. presented graphically. To simplify, form criteria defining on/off moments turbine/pump turbine operating mode adopted. All...

In this paper we analyze whether real-time compensation of wind power plant deviation penalties is profitable by means of the coordinated optimization of the wind power plant with a pumped-storage hydro-plant. We shall make use of optimal control techniques to carry out the optimization. We shall also analyze another possible solution based on compensation carried out a posteriori, instead of i...

This paper presents a novel method based on an enhanced firefly algorithm (EFA) to solve scheduling hybrid thermal, pumped-storage, and wind plants. Since the problem is inherently discrete, basic EFA binary encoding/decoding techniques are used in proposed approach. Optimal power values of thermal pumped-storage units determined separately presence uncertainty caused by speed. The applied real...

A host of technologies has been developed to achieve these aims of the smart grid. Some of these technologies include plug-in electric vehicle, demand response program, energy storage system and renewable distributed generation. However, the integration of the smart grid technologies in the power system operation studies such as economic emission unit commitment problem causes two major challen...

The paper addresses the unit commitment problem in power plant operation planning. For a real power system comprising coal and gas red thermal as well as pumped storage hydro plants a large-scale mixed integer optimization model for unit commitment is developed. Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported.
