An intelligent micro grid controller system with over current protection capability in both the grid-connected and the islanded modes of operation is proposed. To achieve the above strategy a model of small portion of distribution network as if it were a micro grid will be developed and considered. The processor based relays that provide over current protection functions in addition to performing control, measurement, and communication functions will be suitably employed. © 2015 IEEE.

Modern Control Methods for Adaptive Droop Coefficients’ Design

A microgrid is a localized grouping of electricity sources and loads i.e. it is a small-scale power grid that normally operates connected to the centralized grid but can also disconnect and function autonomously. This papers proposes a LabVIEW based Central Protection Center (CPC) that remotely monitors a grid-connected microgrid using a wireless medium. The microgrid is divided into zones for ease of monitoring. The CPC is capable of continuously capturing the current status of the grid in a zonalised manner. If a fault is diagnosed by the central protection center, then it issues appropriate overcurrent relay coordination to the microgrid network. © 2018 IEEE.

Wi-Fi Based Central Protection Center for Microgrids

Microgrids comprise low voltage distribution systems with distributed energy resources (DER) and controllable loads which can operate connected to the medium voltage grid or islanded in a controlled and coordinated way [1]. Microgrids are controlled units which report their current state to a central control unit called Central Protection Centre (CPC) thus increasing reliability of the system. This feature also increases the controllability, security and ease of power flow. By connecting load centers to a microgrid, uninterrupted power is supplied to households and industries with reduction in energy theft, interruptions and loss in energy. However the challenge lies in automating the entire process of monitoring, protection and control of all the grid parameters. This becomes more critical with inclusion of DERs as they are inconsistent sources of energy. In this paper the concepts of Internet of Things(IoT) is used to solve the issues of microgrid reconfiguration occurring due to faults, changing energy usage patterns and inclusion and removal of DERs. By using suitable processor based technology it is aimed to automate the process, reduce the cost and size of establishment and reduce the overall cost of energy to the supplier. © 2018 IEEE.
