“…A lot of research works are going on across the world to look for a new HPS technology for the last two decades [15][16][17][18]. A number of studies have given importance to the physical structure of the renewable power plant and its mathematical modeling [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Such a case of isolated wind energy based HPS that relies on the relationships between the wind station size (WS)/location, variable reverse power flow (VRPF), and demand level is investigated with the constraint of the maximum feasible WS size and VRPF under zero, and are discussed for the active-reactive optimal power flow in the different demand scenarios to ensure energy losses [34,35].…”

Concerned with the increasing greenhouse gases in the atmosphere due to fossil fuels, the entire world is focusing on electricity generation through renewable energy resources. The most advantageous aspect of the distributed renewable sources is to provide the electricity to remote, scattered and the deprived rural areas by developing the hybrid power system at the smaller scale where power transmission through grid extension is not viable due to some economical, technical or environmental constraints for building new transmission lines. An accurate and adequate control strategy becomes inevitable to uphold the smooth operation by restraining the frequency and voltage deviation within its limit ensuring the highest degree of reliability of hybrid power system to provide an adequate power quality. In this paper, a comprehensive review of different control strategies adopted in isolated and interconnected multi-area hybrid power systems is presented.

“…Modern thinking views wind derived energy as a shield against ever increasing oil-power prices. The literature indicates that wind energy (being free, sustainable/ end-less, indigenous, site-dependent, promising, nonpolluting, benign) is being rigorously pursued by a number of countries (with average wind speeds in the range of 4 to 10 m/s), in an effort to reduce their dependence on fossil-based, non-renewable fuels (Amr et al 1990, Nayar et al 1991, Evans 1992, Swisher and Gipe 1992, Bellarmine and Joe 1996, Daoo et al 1998, Nfaoui et al 1998, Rizk et al 2001. Cumulative global wind energy capacity expanded to 59,094 MW in 2005.…”

The recent increase in energy costs, driven by a surge in oil prices, has increased world-wide efforts on the exploitation of renewable/wind energy resources for environment-friendly sustainable development and to mitigate future energy challenges. Moreover, experience in the wind energy industry has reached high levels in the field of manufacturing and application. This inevitably increases the merits of wind energy exploitation. In order to exploit wind resources, through the establishment of wind power plants, specific attention must be focused on the characteristics of wind and wind machines. The literature indicates that wind-energy resources are relatively better along coastlines. In the present study, long-term hourly mean wind speed data for the period 1986-2003, recorded at Dhahran (Eastern Coastal region, Saudi Arabia), has been analysed to examine the wind characteristics including (but not limited to): yearly/monthly/diurnal variations of wind speed, frequency distribution of wind speed, impact of hub-height/machine-size on energy production, etc. Data have been checked/validated for completeness. Data analysis indicated that long-term monthly average wind speeds ranged from 3.8 to 5.8 m/s. Concurrently, the study determined monthly average daily energy generation from different sizes of commercial wind machines (150, 250, 600 kW, etc.) to assess the impact of wind machine size on energy yield. The study also estimated annual energy production (MWh/year) from wind farms of different capacities (3, 6, 12, 24 MW, etc.) by utilising different commercial wind energy conversion systems (WECS). It was observed that, for a given 6 MW wind farm size, a cluster of 150 kW wind machines (at 50 m hub-height) yielded about 32% more energy when compared to a cluster of 600 kW wind machines. The study also estimated the cost of wind-based electricity (COE, US$/kWh) by using different capacities of commercial WECS. It was found that the COE per kWh is 0.045 US$/kWh for 150 kW wind machine (at 50 m hub-height) whereas COE was 0.039 US$/kWh for 600 kW wind machine (at 50 m hub-height). The study also dealt with wind turbine characteristics (such as capacity factor and availability factor). These characteristics are important indicators of wind turbine performance evaluation.

“…It has been established that the location for wind energy conversion systems installation must be selected based on factors such as high mean wind speed, acceptable daily, seasonal variations and both limited turbulence levels and extreme winds (Bansal et al, 2002). Benefits obtained from energy system for small rural communities fall into three categories namely energy to improve livelihood; to improve agricultural productivity and for small scale industries (Nayar et al, 1991). In 2005, the energy sector targeted to establish at least 50 MW wind farm along the coastal plains, and also to introduce 50 small wind turbines of 1 kW capacity in off-grid locations with good moderate wind speeds.…”

The cost of extending electrical power systems to remote areas is expensive and the option is to decentralise small scale energy power systems that could meet the demand in those areas. Wind potential at selected locations in Ghana has been studied for wind energy purpose since there is an increase in socio-economic development in the country. Four (4) of the three-cup anemometers and data-loggers were installed on a 20-m and 30m masts at Amedzofe, Anloga, Areeba-Nkwanta and Kue-Nkwanta (all in the Volta region). The recorded data were analyzed using STATISTICAL software and calculations were made to obtain the Weibull distribution two-parameters and prediction for hourly, monthly mean wind speeds and mean wind power densities were predicted at 50 m above ground level. Among the selected sites, the mean wind power density of Amedzofe and Anloga fell into Classes 3 and 6 of the commercially international system of wind classification respectively, while Areeba-Nkwanta and Kue-Nkwanta fell into Class 2. Anloga is therefore a suitable site for wind power generation to serve the community. Keywords: Wind power potential; Wind atlas analysis and application program (WAsP); Weibull distribution; Wind speed; Wind power density.
