Current demand response (DR) programs are designed for wholesale markets and utility level issues, neglecting the local challenges that distribution network operators face during daily operations. On the other hand, deployment of DR in specific parts of a distribution network can enable additional services and benefits. Phase balancing, as a distribution system management requirement, is among them. This study is one of the first efforts on field testing of phase balancing through load management in residential and commercial buildings. Tests were conducted in an experimental facility to quantify the impact of corrective management actions on phase loadings.
