Flexible D-agent architecture for DER operation in a rural Indian microgrid

This paper outlines the architecture and functions of a D-agent based control and coordination framework for a typical rural Indian microgrid. The microgrid topology consists of independent agents for the storage bank, solar PV array, biogas generator and fixed load. The algorithm of the D-agent has been developed to ensure optimal load servicing by dynamic resource allocation for increased operational efficiency. The operational algorithm has been verified using three different design test cases at an hourly interval of system operation for a period of one year. Low system cost, servicing efficiency and balanced utilization of the Distributed Energy Resources (DERs), are the proposed design test cases. These cases verify the flexibility of the D-agent algorithm. The D-agent ensures optimal utilization of available resources while providing maximum servicing of loads. This is achieved by monitoring and controlling the DER operation based on the current energy availability and load demand for the next interval of system operation.
