Abstract
This paper proposes a power flow analytical technique for a networked microgrid for grid-connected and islanded operations. This technique is convenient for solving the power flow of different topologies due to the changes in the switching status of interconnected switches in the planning and operating stages. Furthermore, it can be used to calculate the bus voltage, line flow, and system loss for scheduling and dispatching the battery energy storage system in energy management systems. First, the bus and branch data of the sample system were established in the OpenDSS software. Next, the load, photovoltaic, and the battery energy storage system data from the database were obtained from the metering system. Second, the OpenDSS, InfluxDB database, and Grafana web-based visualization tool programs were integrated with Python language. Then, the OpenDSS can solve the power flow after the switching state is changed. Finally, the proposed approach was used to solve the power flow of a networked microgrid under different operating conditions. The numerical results demonstrate that the proposed analytical technique helps solve the power flow of networked microgrids.
