Abstract
Steady state analysis of primary distribution system is an integral part of Micro Grid (MG) planning, design and operation of distribution system. In order to maximize performance and ensure secured operation of distribution system with MG, it is important to perform various analytical studies, both in static and dynamic domains. Static studies are the first step and static performance can be established by looking at a number of stead state aspects such as total power losses, voltage profile, feeder current and load ability of the system. This study presents such first step static analytical studies based on distribution load flow to see various steady state performances of primary distribution system due to the integration of MG. A 33-bus test distribution system has been used to present steady state performances. Results clearly show some useful contribution of MG in improving distribution system performance.
Highlights
Micro Grid (MG) can be defined as a group of DG units and load operating as a single entity and is integrated into a distribution system and operates in self-coordinated and independent manner
This study presents comparison the voltage profile of the distribution system studied when it operates with and without MG
With the introduction of MG there is a drastic reduction in the feeder current
Summary
Micro Grid (MG) can be defined as a group of DG units and load operating as a single entity and is integrated into a distribution system and operates in self-coordinated and independent manner. It appears to grid as a single load. During island mode of operation, depending upon load and generation capacity of the system, either total load or only a part of load will be supplied by MG It means there may be a partial load shedding to match load demand and generation in distribution system where MG is located (Katiraei and Iravani, 2006)
