The real-world performance of inverters is investigated across their full range of operation, concentrating on harmonic distortion and power factor. The inverters under review are representative of a cross-section of the UK market in terms of price and device quality. They include both voltage and current source converter topologies. The test results are compared against the relevant clauses of the...
Conservation voltage reduction (CVR) is an energy conservation tool that various network operators have used to manage demand on their networks over the past few decades. Renewed interest in this approach, coupled with the changing composition of domestic electricity demand has prompted debate about the role of CVR within future networks. This paper discusses some of the contemporary power quality...
Thermal energy storage (TES) can be used to shift air-conditioning (A/C) load and thus reduce peak electricity demand. A case study is presented for Saudi Arabia, within which a high penetration of small-scale residential A/C systems is prevalent. A model that estimates A/C usage for the selected network is developed. Historical demand data is used to forecast the holistic impact of extensive TES...
