The Joint Working Group C4.24, Power Quality (PQ) and EMC Issues associated with future electricity networks, is a joined working group of CIGRE and CIRED, which collaborates with a IEEE working group "PQ Issues with Grid Modernization", whose scope and objectives are similar. The group obtained its mandate in 2013 and it addresses, according to its scope, the following issues: - The emissions (harmonic and unbalance) by new types of devices connected to the distribution network as production (DG) or consumption (load), especially devices with an active power electronics interface including equipment connected to low-voltage and installations connected to higher voltage levels. This might require the evaluation of new measurement techniques, including a closer look at the frequency response of existing instrument transformers and sensors. The main question is: will this require new ways of considering PQ in the design? - The positive and negative impact of new smart distribution applications such as Volt &VAR control, and feeder reconfiguration on PQ (voltage unbalance and harmonic flow) in the distribution system. - How these PQ issues at the distribution level may impact the transmission system. The group has currently about 30 members and holds several meetings each year. Its work on different subjects, referred to as "chapters" will likely correspond to chapters in the "Technical Brochure", which is scheduled for late 2016. The list of chapters includes: 1. Introduction, scope of the report and terminology, 2. New developments in power electronics (PE), 3. Overview of smart grids and power quality, 4. Changes in probability of interference, 5. Microgrids and PQ, 6. Volt & VAR control and PQ, 7. Feeder reconfiguration and PQ, 8. Demand side management and PQ, 9. New measurement techniques, 10. New mitigation, 11. PQ and economics.

Abstract

The Joint Working Group C4.24, Power Quality (PQ) and EMC Issues associated with future electricity networks, is a joined working group of CIGRE and CIRED, which collaborates with a IEEE working group "PQ Issues with Grid Modernization", whose scope and objectives are similar. The group obtained its mandate in 2013 and it addresses, according to its scope, the following issues: - The emissions (harmonic and unbalance) by new types of devices connected to the distribution network as production (DG) or consumption (load), especially devices with an active power electronics interface including equipment connected to low-voltage and installations connected to higher voltage levels. This might require the evaluation of new measurement techniques, including a closer look at the frequency response of existing instrument transformers and sensors. The main question is: will this require new ways of considering PQ in the design? - The positive and negative impact of new smart distribution applications such as Volt &VAR control, and feeder reconfiguration on PQ (voltage unbalance and harmonic flow) in the distribution system. - How these PQ issues at the distribution level may impact the transmission system. The group has currently about 30 members and holds several meetings each year. Its work on different subjects, referred to as "chapters" will likely correspond to chapters in the "Technical Brochure", which is scheduled for late 2016. The list of chapters includes: 1. Introduction, scope of the report and terminology, 2. New developments in power electronics (PE), 3. Overview of smart grids and power quality, 4. Changes in probability of interference, 5. Microgrids and PQ, 6. Volt & VAR control and PQ, 7. Feeder reconfiguration and PQ, 8. Demand side management and PQ, 9. New measurement techniques, 10. New mitigation, 11. PQ and economics. This paper gives a status report of work achieved by the group members after eleven meetings and also provides interesting details for some of the chapters in the following order: "Findings", "Recommendations" and "On-going discussions".
