Power Dispatching of Active Generators Using Droop Control in Islanded Micro-Grid
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
The Microgrid(MG) concept allows small distributed energy resources (DERs) to act in a coordinated manner to provide a necessary amount of active power and ancillary service when required. This paper presents control and power management of electronically interfaced Distributed Energy Resource (DER) units for microgrids. Voltage and frequency regulation in an islanded microgrid is one of the main control requirements. In this work, inverter control method for islanded operation of microgrid for the renewable resources has been studied. First task of the study was development of a Voltage Source Converter (VSC) system. Active and reactive power control systems for power dispatching have been implemented in the VSC and so that it can work as an active generator. The power dispatching policy of the active generator is based on combination of droop and PI control method. This paper presents results from a test microgrid system considering of a voltage sourced converter VSC interfacing with a DG under varying load conditions. The model has been simulated in MATLAB/Simulink and stable operations have been observed where micro-grid frequency, voltage and power quality were within acceptable ranges.
