What is it about?
Customers at the distribution network end of the electric power delivery chain need to receive electric power at the standard voltage and frequency of supply. This is often not the case due to several technical reasons. One of such problems is voltage imbalance across the 3 phases. This paper presents a methodology for mitigating this problem using DVR.

Why is it important?
This is critical to ensuring good power quality supply to customers.
Perspectives
In designing electric power networks or implementing major expansions to existing networks, a number of the key issues regarding the technical performance of the network at both transmission and distribution level must be ascertained. These include: (i.) Voltage regulation (ii.) Voltage fluctuations Rapid voltage rise (RVR) (iii.) Electrical losses (iv.) Distribution plant loading and utilization (v.) Fault level (vi.) Generation stability (vii.) Harmonics (viii.) Phase balancing (ix.) Supply availability and (x.) System security This paper is an excellent contribution to the body of knowledge in this area of phase balancing.
