Development of Protection Scheme for Off-Grid Topology

In the field of energy, there are themes such as decentralized electricity production, the use of renewable energy sources, such as photovoltaic and wind power plants for self-sufficient energy supply of buildings or objects in the so-called Off-Grid island autonomous systems. Traditional distribution networks are facing new opportunities and challenges, considering the protection scheme and control technology. This paper proposes a new approach to use Adaptive protection scheme to limiting of at failure states and abnormal operation states, such as short-circuits and overloads in an autonomous single phase Off-Grid systems. Developed by the Adaptive protection scheme is able to change and configure itself for various operation states in the Off-Grid system. In addition, the proposed Adaptive protection scheme is based on central control and real-time analysis of data acquired from conventional electronic measuring devices.
