This paper presents a simple and efficient operating strategy for the operation of Pumped Storage Hydro (PSH) plant so as to maximize the profit of the Wind-Thermal-PSH hybrid plant with considering the grid frequency (f) and current energy level of the PSH plant. The wind speed is predicted for a day-ahead market and with this predicted value of wind speed the wind plants are committed to supp...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

Due to the rapid growth in the amount of wind energy connected to distribution grids, they are exposed to higher network constraints, which poses additional challenges to system operation. Based on regulation, the system operator has the right to curtail wind energy in order to avoid any violation of system constraints. Energy storage systems (ESS) are considered to be a viable solution to solv...

This paper proposes an efficient optimization approach to determine the optimal placement and size of Static VAR Compensator (SVC) in a hybrid power system. The hybrid power system consists of conventional thermal generators, wind farms and solar photovoltaic (PV) modules. In this paper, the optimal placement and size of SVC is determined by considering the voltage deviations minimizations and ...

This paper examines the effects of increased intermittency, caused by climate change, on strategic hydroelectric production when wind power is integrated with hydroelectricity. It is shown that increased uncertainty in water inflows caused by climate change raises hydroelectric output and increases the probability of overflow in future periods. The increased variability of wind speeds due to cl...

The continuous improvement of the accuracy of wind power forecasts is motivated by the increasing wind power integration. Today forecasters are challenged in providing forecasts able to handle extreme situations. This paper presents two methods focusing on forecasting large and sharp variations in power output of a wind farm called ramps. The first one provides probabilistic forecasts using lar...

in this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of iran. four stations in khuzestan- abadan, hosseyneh, mahshahr, and shushtar- are analyzed to determine the potential of wind power generation in this province. from the primary evaluation and by determining mean wind speed and also the weibull funct...

Accurate wind speed forecasting is becoming increasingly important to improve and optimize renewable wind power generation. Particularly, reliable short-term wind speed prediction can enable model predictive control of wind turbines and real-time optimization of wind farm operation. However, this task remains challenging due to the strong stochastic nature and dynamic uncertainty of wind speed....

A stochastic programming approach is proposed in this paper for the development of offering strategies for a wind power producer. The optimization model is characterized by making the analysis of several scenarios and treating simultaneously two kinds of uncertainty: wind power and electricity market prices. The approach developed allows evaluating alternative production and offer strategies to...
