6 FAQs about [Nanji island energy storage]
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.
How reliable is Nanji Island power supply?
As for the construction of Nanji Island, a high reliability microgrid technology is demonstrated with a dual-microgrid structure, which can support each other. Although the power supply reliability can reach 99.99%, the cost of construction increases by about 20%. In the control strategy, DE is necessary in the power supply configuration.
Does Nanji Island use off-grid power supply?
The island has plenty of sunshine and strong sea breeze, and the island uses off-grid power supply; This article uses Nanji Island as the analysis object to optimize the capacity configuration of wind–solar–diesel–storage combined system, and verifies the feasibility of the scheduling strategy proposed in this paper.
How many generators does Nanji Island have?
The microgrid on Nanji Island is equipped with one 500 kW DE generator and four 300 kW DE generators (Fig. 4). This configuration yields the operating power ranging from 90 kW to 1200 kW, as shown in Fig. 8. If the four 300 kW DE generators were replaced by two 600 kW DE generators, the corresponding range is from 180 to 1200 kW.
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.
What control architecture does Nanji Island use?
All three island microgrids use a three-layer control architecture that consists of a monitoring and scheduling layer, a coordinated control and protection layer, and a local equipment layer. The control architecture of the microgrid on Nanji Island is the most complex among the three microgrids.
