Unbalance - Open Access .click

IEEE Transactions on Power Delivery, 2001
This paper endeavors to present a comprehensive summary of the causes and effects of voltage unbalance and to discuss related standards, definitions, and mitigation techniques. Several causes of voltage unbalance on the power system and in industrial facilities are presented as well as the resulting adverse effects on the system and on equipment such ...

Unbalance compensation control in microgrids based on the unbalance profile

Electric Power Systems Research, 2021
Abstract Voltage unbalances are a common issue in microgrids (MGs), especially under islanded operation. In these conditions, distributed generators (DGs) can be used as compensating devices. Currently, the compensation techniques based on DGs focus on a specific point of the grid, usually the Point of Common Coupling (PCC) or a Sensitive Load Bus ...

The Unbalance of Set Systems

Graphs and Combinatorics, 2008
The authors present the following nice result: If the unbalance of an intersecting family of sets \( \mathcal{F} \) is defined as \( u(\mathcal{F}) = |\mathcal{F}|-d(\mathcal{F}) \) where \( d(\mathcal(F)=\max|\{F\in\mathcal{F}:x\in F\}| \), where the maximum is taken over all vertices x, then for k-uniform intersecting families \( u(\mathcal{F}) \leqq
