Economic needs and the ongoing liberalization of European electricity markets stimulate the interest of power utilities in developing models and optimization techniques for the generation and trading of electric power under uncertainty. Utilities participating in deregulated markets observe increasing uncertainty in load (i.e., demand for electric power) and prices for fuel and electricity on s...

Small DC networks to communicate effectively with a variety of output sources such as photovoltaic systems and wind energy storage systems,. If in addition the system DC power is fed over the need to transform and rectify AC network resources compared with a small decrease. Use most of the renewable energy the different factors fine network operates independently suggestions have been. When the...

Modeling of regulating system of large pumped storage power station with long pipeline and parameters optimization in transient processes are studied in this paper. According to the actual parameters of a certain pumped storage power station, MATLAB/Simulink toolbox is utilized for modeling and simulation of its subsystems. Friction resistance coefficient and water elasticity are taken into con...

Pumped storage hydro units (PSHU) can provide flexibility to power systems. This becomes particularly valuable in recent years with the increasing shares of intermittent renewable resources. However, due emphasis on thermal generation current market practices, from PSHUs has not been fully explored and utilized. paper proposes a configuration based pumped (PSH) model for day-ahead market, order...

At present, Energy storage systems are widely used in power supply, grid and end-users system. There have been extensive application explorations most scenarios China, such as smoothing fluctuation output tracking of new energy sources, assisting conventional units to participate frequency modulation, peak-shaving modulation the grid, system standby, peak-valley arbitrage load side, well demand...

Transition from fossil fuels to renewable sources is inevitable. In this direction, variation and intermittency of renewables can be integrated into the grid by means of hybrid systems which operate as a combination of alternative resources, energy storage and long distance transmission lines. In this study, we propose a two-stage stochastic mixed-integer programming model for sizing an integra...
