Microgrid is known as a distributed energy resource group that functions as a group classified into a number of microgrids, to facilitate robust control and operation infrastructure in future distribution systems. The control and design of the inverter and the technique of operating the microgrid testbed in stand-alone or parallel can affect the system
The parallel of inverters is inevitable in the operation of distributed generation with a Microgrid. However, due to the difference in line impedance between each parallel inverter and the public AC bus in the microgrid, the m available control method is insufficient to overcome the disadvantages such as unbalancing distribution of power, large circulating current, and poor

When connected to the unbalanced load, a three-phase microgrid inverter (MGI) based on traditional droop control would produce an unbalanced output voltage, which will lower the system''s power quality.

Schneider Electric Indonesia. Implement and operate your microgrid to produce and consume local energy. Monetize the value of your DER, optimize your bill, and avoid interruptions.
The exciting answer for organisations is “it’s free” because an energy-as-a-service (EaaS) approach eliminates your upfront costs. A microgrid, in a more traditional way, is a CapEx and an OpEx model. In a project mode, it’s high CapEx and low or no OpEx, in an energy-as-a-service business model, it’s high OpEx.
