PLC Based Load Sharing of Transformers

Discrete-Event Supervisory Control for Under-Load Tap-changing Transformers (ULTC): from synthesis to PLC implementation

Reliability Assessment of Distribution Transformers Considering Load Harmonics

The progressive application of non-linear loads in distribution systems (DS) increases current harmonics flow in DS's apparatuses, especially distribution transformers (DTs). Since DTs' operating temperature rises due to the harmonics flow, their loading should be reduced such that the hot spot temperature (HST) is preserved under its permissible value. This means that DTs' available capacity i...

Examination of Free Capacity Based Load Sharing

Sophisticated traffic engineering (TE) methods are currently under development. The price for broad TE functionality is high, especially in complexity and scalability. Moreover, there are several specialised networks where simpler TE mechanisms are required because of computational or scalability limitations. Such a simpler TE solution is load sharing. Currently, the performance of load sharing...

Exploring Threshold-based Policies for Load Sharing

We consider the problem of how to design resource allocation policies that both provide good performance at predicted environmental conditions and are robust against changes or misprediction of the environmental conditions. We evaluate various common threshold-based allocation policies within a simple model, where there is a clear tradeoff between the (conflicting) goals of good performance and...

Voltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer

Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...
