Island Microgrid Remote Monitoring

Do microgrids detect islanding?

Table 3 shows that in all the cases considered for microgrids and changes in supply and demand, as well as changes in the exchange power between the power system and the distribution network, the islanding detection was well performed. The maximum frequency deviation occurs at 12° and the minimum frequency deviation occurs at-12°.

How is islanding performed in a microgrid?

At t = 6s, islanding is performed using the switch that exists between the microgrid and the upstream power grid. In this microgrid, the solar source includes a PV panel that converts solar power to DC power, and using an IGBT-based inverter, DC power is converted to three-phase AC power.

What control technology is used for the three island microgrids?

In what follows, we introduce the coordinated control technology used for the three island microgrids from four aspects: hierarchical control architecture, mode switching technology, stability control, and black start control. 3.6.1. Hierarchical control architecture based on the IEC61850 standard

What are the island microgrids?

Table 1. Summary of the island microgrids. Recently, three unique stand-alone microgrid projects have been built at Dongfushan Island, Nanji Island, and Beiji Island in the east China, with an aim to replace diesel with renewable energy to improve renewable energy utilization, enhance power supply reliability, and reduce power supply cost.

What is the Maui Island microgrid?

The Maui Island microgrid is built on the island of Hawaii . A 10 MW lithium-ion-based battery energy storage system (BESS) is designed to maintain the load frequency control by dispatching regulating reserves of active power to a 91 MW test section of the Maui Island grid model with WT of 30 MW.

Are microgrid systems a good option for Islands?

With the technological advance and the declining comprehensive cost, the advantages of microgrid systems on islands will be increasingly pronounced. We acknowledge the financial supports from National Natural Science Foundation of China (51507094 and 51537003). Chris Marnay.
