The integration of wind power in power systems results in a reduction in greenhouse gas emissions. Thus, it has a positive environmental impact. However, the operation of these power systems becomes increasingly complex, owing mainly to random behaviour of the wind. In the case of island power systems, this problem is even more difficult. The traditional solution is to use diesel generators as ...

This paper presents a new evaluation model of wind-Photovoltaic (PV)-thermal-pumped storage integration system considering carbon emission. The is constructed on the basis comprehensively construction cost, operation start-up and shutdown cost unit, wind abandonment rate, PV rate emission fully utilizing power curtailments PV. It analyzes electric energy benefit low-carbon economy in three diff...

The laws of fluid mechanics imply that modular offshore pumped hydro-energy storage systems like StEnSEA have no advantage over similar but much cheaper onshore systems.

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.

In this paper we present an algorithm, inspired by the cyclic coordinate descent method, which allows the resolution of hydrothermal optimization problems involving pumped-storage plants. The proof of the convergence of the succession generated by the algorithm was based on the use of an appropriate adaptation of Zangwill’s global theorem of convergence.

We consider the problem of the optimization of the functioning of a pumped-storage hydroplant. The problem can be mathematically formulated as an optimal control problem, and when the considered hydromodel is of the fixed-head type, an added complication arises: the solution is of the bangsingular-bang type. In this paper, we propose a simple and efficient optimization algorithm to find the sol...
