6 FAQs about [Pcc microgrid Tajikistan]

What is the primary and secondary level of a microgrid?

The primary level is in charge of droop control of power electronic interfaces. The secondary level controls voltage/frequency restoration and synchronisation of microgrids in case of any variation in load or generation, as well as in islanding mode.

How are microgrids controlled?

Control of microgrids is one of the challenges that operators usually face with it. Microgrids are controlled in three hierarchical levels namely primary, secondary, and tertiary ones. The primary level is in charge of droop control of power electronic interfaces.

Are microgrid owners the same?

Generally, the owners of microgrids are not identical; therefore, each microgrid tries to optimise its own profit and maximise its utilisation of the point of common coupling (PCC) capacity to boos...

What happens if a microgrid confronts a generation surplus?

In normal condition, if a microgrid confronts generation surplus, the extra power will be sold to the grid and in case of power deficit, the required power will be purchased from the grid. The power purchased from the grid is usually more expensive than power sold to the grid [ 1 – 3 ].

What is the profit of a whole microgrid?

Thus the profit of whole microgrids would be equal to $7275. In this scenario, the introduced aggregator provides the microgrids with day-ahead grid prices. Subsequently, microgrids implement their self-scheduling considering PCC capacity and report the corresponding power exchanges (with the grid) to the aggregator.

What is the aggregator of a jth microgrid?

The numerator of ( 36) is the sum of surplus exchangeable power of the j th microgrid and the denominator is the sum of exchangeable power of all microgrids at the time period of 24 h. In this scenario, the aggregator allows MG1, MG2, and MG3 to use 38, 38, and 24% of common line/transformer capacity.
