Dr. Nokhum S. Markushevich (M) has more than 50 years of experience in power system operations, research and education. He worked for the Latvian Power System for 29 years and was an Associate Professor in the Latvian Institute of Advanced Education. He has lived in the U.S. since 1990 and has provided consulting services to utilities in North America and South East Asia. He was Domain Leader and Principal Investigators in a number of EPRI-sponsored Intelligrid and Smart Grid projects, as well as in Smart Grid studies for utilities. He is an active member of the Smart Grid Interoperability Panel Domain Expert Transmission and Distribution and Distributed Energy Resource Working Groups and the IEEE 1547.8 Working Group. At present, he is President of Smart Grid Operations Consulting (Sunnyvale, CA). He has authored several books and more than 100 papers and inventions on power system operations, Smart Grid, EMS, and DMS.

The variable operations of weather-related Distributed Energy Resources in distribution systems cause voltage fluctuations at different buses of the distribution circuits. These fluctuations may significantly impact the power quality as well as the reliability of other volt/var controlling devices. Compensating changes of the DER reactive power may be used to mitigate these voltage fluctuations. This paper discusses two methods of such compensation, compares them in terms of a number of operational criteria, and presents an illustrative numerical example.
There is a notion common among many power industry engineers that improving the power factor on the distribution feeders and lowering the electrical losses will also reduce the amount of energy that must be purchased from the energy supplier to serve a given customer load.
