This research paper presents a look-ahead optimal control strategy for a Hydro-static Drive Wind Turbine when look ahead wind speed information is available. The proposed predictive controller is a direct numerical optimizer based on the well established principles of Hamilton-Jacobi-Bellman (Dynamic Programming). Hydro-static transmission based, non-linear model of wind turbine is used in this optimization work. The optimal behavior of the turbine used the non-linearity of aerodynamic maps and hydro-static drive train by a convex combination of state space controller with measurable generator speed and hydraulic motor displacement as scheduling parameters. A comparative analysis between a optimal controller based on Maximum Power Point Tracking (MPPT) algorithm as published in literature and the proposed look ahead based predictive controller is presented. The simulation results show that proposed look ahead strategy offered optimal operation of the wind turbine by closely tracking the optimal tip-speed ratio to maximize capacity factor while also maintaining the hydraulic motor speed close to the desired value to ensure that the frequency of electrical output is constant. It is observed from the simulation results that the proposed predictive controller provided around 3.5% better performance in terms of improving total system losses and harvesting energy as compared to the MPPT algorithm.

Wind energy is one of the cheapest sources of energy that may solve the Climate change problem and fresh water scarcity challenges. This article introduces a novel Desalination Wind Turbine that is cheaper and more efficient than the common wind turbine, especially offshore wind turbines. In this system, the wind energy transmitted to the water pump by a hydraulic transmission line. The RO module is used for fresh water production. The pressure recovery module is added to RO system, to increase the permeated flow. It can be increased the permeate flow up to 45%, which is significant. The Maximum Power Point Tracking (MPPT) based on the hydraulic oil pressure measurement is implemented. In addition, the Maximum Permeate Flow Tracking control loop, similar to MPPT, is introduced to optimized the pressure of the RO system. It is increased the annual permeate production up to 8%. The long term performance of the system, such as annual water production is calculated and the ability of the system to MPPT and the wind turbulence and gust is analyzed. The rotor speed overshoot of the closed loop system is less than 16%, which is acceptable.

“…Therefore, renewable energy is very popular in the world, and wind energy is one of the important sources of clean energy. A wind turbine converts wind energy to the electrical energy, which is transmitted to the consumers by using transmission power lines (Rajanbhandharaks(2014). This electrical energy may be consumed to produce fresh water (Masters 2017) .…”

The climate change and water scarcity are the most world environmental challenges.Producing fresh water from seawater needs a lot of energy that may be supported by fossilfuel power stations. However, a solution for the challenges is water desalination system thatis integrated to the renewable energy. Moreover, there is much energy conversion in thesesystems that reduce the overall system efficiency. This article introduces a novel DesalinationWind Turbine, and such that it is described and analyzed by nonlinear simulation. In thissystem, the wind energy transmitted to the water pump by a hydraulic transmission line. TheRO module is used for fresh water production. The long-term performance of the system,such as annual water production is calculated and the ability of the system to Maximum PowerPoint Tracking and the wind turbulence and wind sudden change is analyzed, which showsthe system overshoot is less than 6%.
