Latest information on Kaishan Island Microgrid

What power sources are in the Nanji Island microgrid?

The Nanji Island microgrid contains four types of power sources: wind power, solar power, DE, and energy storage. The lithium batteries have three operating modes: P/Q, constant V/F, and droop control. DEs have P-F and Q-V droop control modes. WTs, PV units, and super capacitors have P/Q operating mode only.

What is the control system for the Nanji Island microgrid?

The control system for the Nanji Island microgrid is based on the IEC61850 standard , which coordinates the three control layers using an MMS protocol for between-layer communication and a GOOSE protocol for within-layer communication.

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.

What are the different types of Island microgrids?

The different types of island microgrids are summarized in Table 1. In general, there are five types of island microgrids, including PV/WT/Diesel, PV/Diesel/Battery, WT/Diesel/Battery, WT/Diesel/Flywheel, and PV/WT/Diesel/Battery. The installed capacity of renewable energy ranges from dozens of kilowatts to a few megawatts.

What is the EMS for the microgrid on Nanji Island?

The EMS for the microgrid on Nanji Island is relatively complex due to the large rated capacity and aggregate load. The load on this island is classified into important load, shiftable load, and adjustable load by the controllability of load.
