6 FAQs about [Power Grid Dispatching Micro-class Lecture Content]

What is autonomous load sharing among dispatchable DG units?

(i) Autonomous load sharing among dispatchable DG units takes place as per primary droop control strategy. Active power and reactive power are shared as per P – f and Q – V characteristic, respectively, in an AC sub-grid; active power is shared as per I – V or P – V characteristic in a DC sub-grid [ 4 – 7 ].

What are the operational attributes of a hybrid microgrid?

The operational attributes of an AC–DC hybrid microgrid, and load and renewable generation uncertainties are incorporated in the optimal scheduling problem by using a customised power-flow technique, and by modelling uncertainties by Hong's two-point estimate method, respectively.

Is an AC–DC hybrid microgrid a good choice?

An AC–DC hybrid microgrid is gradually becoming popular. For economic viability and environmental sustainability, an AC–DC microgrid should be operated optimally.

How does power transfer between AC and DC sub-grids take place?

(ii) Power transfer between AC and DC sub-grids takes place autonomously via inter-linking converters depending on relative loadings of the sub-grids. Several suitable operation and control strategies for stable operation of an ADHMG have been reported in literature.

What is autonomous power exchange between AC and DC sub-grids?

Autonomous power exchange between AC and DC sub-grids takes place (via interlinking converter) such that neither the ACMG nor the DCMG are overloaded or under-loaded with respect to each other [ 1 – 4 ]. Due to the above operational features, traditional power flow algorithms are not applicable to an ADHMG.

How do dispatchable DG units work in PQ mode?

Dispatchable DG units working in PQ mode inject constant active and reactive power to the network.
