Power Quality Management in an Off-Gtrid System

The themes such as decentralized electricity production, the use of renewable electricity sources, such as photovoltaic and/or wind power plants for self-sufficient energy supply of buildings or micro grids in the so-called Off-Grid autonomous systems can be found more in the field of energy. Considering, the control technology and power quality of tradition distribution networks is facing new opportunities and challenges. This paper proposes a new approach to use the completely new Power Quality Management (hereinafter the PQM) for to avoid inappropriate or dangerous states and abnormal operation states, such as power quality (hereinafter PQ) limit excess according to the standards in an autonomous single phase Off-Grid systems. The Off-Grid system is controlled by the ADSM (Active Demand Side Management), which is a fully functional control system for Off-Grid system. Developed by the PQM which will be integrated in the ADSM in Off-Grid system, thereby adjusting the consumption plan to keep PQ parameters within the allowed limits. In addition, the proposed PQM is based on centralized control system and the real-time analysis of data acquired from conventional electronic measuring devices in common with the PQ parameters prediction.
