The impact of energy saving technologies on electric distribution system power quality

This paper contains a discussion of several energy saving technologies and their impact on electric power distribution systems. The reduced power demand of these energy saving devices reduces the peak system demand. However, there are increased distribution transformer and distribution network losses due to the distorted load current waveshape. These losses, when integrated over many services and over the year, represent a significant cost due to fuel costs and higher peak. The main focus of the discussion relates to ASD heat pumps and electronic ballast fluorescent lighting.<>
