Power Quality Measurement of Small Solar off-Grid System
Authors: , , , ,
Abstract: Energy from renewable energy sources increase of recent years. This increasing is consequence of reduction of CO2 effort and it reduces the price of renewable energy sources. Development of distributed generation and energy self-sufficient regions supported also by the development of a smart grids research contributes significantly to the diversification of primary energy sources and helps to increase the energy efficiency. Smart grids, distributed generation and self-sufficient off-grid systems are becoming one of the priorities for research in EU Member. The interest in off-grid systems is proved by the number of research and pilot projects. Aim of this paper is presented an example of stand alone low power photovoltaic off-grid system and an analysis of the power quality carried out for the system working to load control system. This load control system was developed to make the tests and simulations of this off-grid system with optional and user predefined load profiles in laboratory environment. In the last part of paper are results from in-situ measurement in small off-grid installation. All the results give information for better knowledge about off-grid operation and power quality.
