Abstract: Wind is progressively being utilized to give a portion of the world's power. Points of interest of wind created power incorporate zero emanations and zero fuel cost. In any case, wind speed differs time to time, at a given time the controller can't handle the most extreme measure of intensity delivered by a turbine. An alternate rule utilized for ideal plan than that utilized for other gear where the pace of power creation can be controlled up to the hardware most extreme rating. The ideal plan for a wind turbine working in each wind asset is the plan that delivers the most electrical energy for a given capital expense. During high winds the particular plan boundaries and control frameworks should restrict the force variance to stay away from harm to the wind turbine. Thusly we should utilize distinctive control frameworks. The reason for the control arrangement of a wind turbine is to deal with the protected, programmed activity of the turbine. From these idea we can lessens working expenses, gives steady unique reaction and improved item quality, and assists with guaranteeing wellbeing. This activity is generally intended to augment yearly energy catch from the wind while limiting turbine loads. In this paper the controlling arrangement of a 2MW wind turbine is examined essentially the pitch control and speed control is quickly investigated by considering the turbine and the generator model by utilizing MATLAB 2018®b.

Abstract: The objective of the study is to provide scientific information of the solar potential of Afar region, for photovoltaic (PV) solar energy industry sectors. The afar region being exceptional solar potential with high average solar radiation flux 239.9W/m2 (105.4% of average photon energy surface area of Ethiopia), and average annual solar density of 2.102MW•h/m2 (105.5% of the average yearly solar density of Ethiopia). This finding requests the photovoltaic system as an alternative principal energy resource to substitute the present energy system in afar region. These comprehensive indication of the solar energy marketplace in Afar region, Ethiopia, key visions into its governing framework, energy sector, of photovoltaic (PV) industry segments. Therefore, the photovoltaic energy system has the best opportunity for basic energy application in the pastoral community for daily life consumption, such as solar lighting, for solar cooker, small devices and for air conditioning. These studies show that the Afar region gifted with significantly high monthly average daily solar radiation as a potential candidate for development of PV energy systems in Afar region. Therefore, the PV system has the power to run an evaporative air conditioning system effectively. These findings indicate that photovoltaic energy system as most promising energy in the Afar region.
