6 FAQs about [Cook Islands structure of microgrid]

What makes the Cook Islands unique?

As a small island developing state, the Cook Islands has unique attributes that considerably enhance the benefits to be gained from renewable electricity. Located in the South Pacific Ocean, the Cook Islands is sandwiched between Tonga to the west, Kiribati to the north and French Polynesia to the east.

What changes will the Cook Islands make?

The changes will include management of power utilities, environmentally friendly and cost effective renewable electricity sources, and energy efficient strategies. The Cook Islands will be careful in its selection of renewable electricity options and will not entertain unproven or non-commercial technologies.

How many islands are in the Cook Islands?

The Cook Islands Located in the South Pacific Ocean, the Cook Islands has 15 islands, of which 12 are inhabited. Most of the Cook Islands 13,000 permanent residents live on Rarotonga, in the south. Aitutaki has a population of approximately 1,800, and remaining islands are sparsely populated. Fig 1.

Where are the Cook Islands located?

Located in the South Pacific Ocean, the Cook Islands is sandwiched between Tonga to the west, Kiribati to the north and French Polynesia to the east. The Cook Islands has 15 islands with a total land area of 240 square kilometres, spread across 1.8 million square kilometres of ocean.

Does the Cook Islands have electricity?

The Cook Islands has a financially healthy electricity sector with technical and commercial challenges requiring on-going investment. With the exception of Pukapuka, Nassau and Suwarrow, the Cook Islands has some form of electricity network. Power supply on Rarotonga is the responsibility of the government-owned utility Te Aponga Uira (“TAU”).

Why do microgrids become more complex than PI-controllers?

The presence of nonlinear factors in the model of some microgrid components causes the microgrid structure to become more complex and the PID-controller to control frequency fluctuations does not perform as well as the PI-controller.
