Advanced Control of A Stand-Alone Wind Energy System

wind and solar energy are the most appealing renewable energy alternatives for producing electrical power. However, due to unpredictable changes in wind speeds, wind resources are uncontrollable. The unpredictable changes cause technological issues like power harvesting and electrical grid disruptions. As a result, Control techniques play an important role in fulfilling the required standards and regulations. The conventional way of realizing the power converter's control structure of wind turbines is through hierarchically organized linear control loops and a pulse width modulator. This structure may be very complex especially when a virtual impedance loop is implemented in case of sharing the power. For the control of power converters, finite control set model predictive control (FCS-MPC) is now a common approach, Because of its adaptability and inherent quickness. This article is looking to discuss using the FCS-MPC solution and considering the current challenges in stand-alone systems. This will enable us to take advantage of its flexibility and fast response. Also, stay away from using linear control loops and instead incorporate the hierarchical control system into a single control unit.
