Abstract: Electric power system is becoming more and more power electronization with each passing day，

additional losses of the power grid caused by the power quality problem is becoming more and more serious with

each passing day. Solving the power quality problem has become the new way to help the power grid to save energy

and reduce consumption. The most common power quality management product is parallel compensation device，it can control the power quality，save energy and reduce consumption，but it is a kind of energy consumption product，therefore its real power savings has become the focus of users. The research status of the relevant standards within the field of inspection and testing was analysed，the research directions of domestic and foreign standards about measurement and verification of energy savings，power savings，power savings for parallel compensation device were summarized. Then the standards system problems about measurement and verification of power savings within the field of inspection and testing were pointed out. At last the development trend of standards system about measurement and verification of power savings from the problem-oriented and market-oriented two aspects was put forward.
