† Fuji Electric Co., Ltd. opment Organization (NEDO) for a period of 5 years beginning in 2003, and has amassed a proven track record for developing and evaluating “microgrid control technology” that balances the supply and demand of energy within a regional grid consisting primarily of renewable energy sources such as solar power, wind power and biomass power. Combining its accumulated advance...

this study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. however due to unpredictable nature...

A new nature inspired metaheuristic algorithm known as the cuckoo search algorithm (CSA) is presented in this paper, to solve the unit commitment problem (UCP) for hybrid power system. The utilization of wind energy sources is increasing throughout the world. It is therefore important to develop the protocol for the integration of wind generation system with conventional thermal unit generation...

Nowadays, propagation of wind turbines make challenges to supply safe power to the grid. Because of wind speed changes, supervisors are concerned to wind turbines, be able to produce appropriate electric power during the wind speed changes. As a matter of fact, investors are mostly like to invest on offshore wind farms, because of their more stable and continuous wind speed rather than onshore ...

One of the main problems in wind energy conversion system (WECS) is how to achieve maxim‌u‌m output power in different wind speeds. Maximum methods for maximum power point tracking in wind energy conversion syst‌e‌ms require the knowledge of system characteristics and mechanic sensors. So, using these methods practically will follow with high price and an abundant difficulties. In this pape...

World wind energy resources are substantial, and in many areas, such as the US and northern Europe, could in theory supply all of the electricity demand. However, the remote or challenging location (i.e. offshore) and especially the intermittent character of the wind resources present formidable barriers to utilization on the scale required by a modern industrial economy. All of these technical...

This article proposes a method to optimize the design of a small fixed-voltage wind energy conversion system (WECS). The system is composed of commercially available elements which are: a small horizontal axe wind turbine, a onestage gearbox, a permanent magnet synchronous generator, a diode bridge and a battery bank. As there are no controlled devices on the system, the design must be carefull...

Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...

At the present time Doubly Fed Induction Generator (DFIG) based wind energy conversion systems are widely used for large wind power plants. DFIG offers many advantages for instance reduced rating power converter, low cost and reduced losses with the better efficiency, easy in realization of power factor correction schemes, variable speed operation and four quadrants active and reactive power co...
