Renewable Energy and Power Quality Journal (RE&PQJ) CIGRE/CIRED JWG C4.112 -Power Quality Monitoring

Abstract. In a response to the renewed interest in power quality monitoring and recognising cross-boundary relevance of power quality monitoring, CIGRÉ Study Committee C4 and CIRED established, in late 2010, the Join Working Group (JWG) C4.112: "Guidelines for Power quality monitoringmeasurement locations, processing and presentation of data". The JWG started work in February 2011 with the aim to address the application aspects of power-quality monitoring, in particular what to measure, how to measure and how to handle recorded data. This paper presents some of the results of the JWG achieved between February 2011 and December 2013, provides recommendations with respect to power quality monitoring depending on identified objectives of monitoring and identifies the areas requiring further development and research in order to comprehensively address the issue of power quality monitoring in contemporary and future power networks

Methods for Analysis and Quantification of Power System Resilience

This paper summarizes the report prepared by an IEEE PES Task Force. Resilience is a fairly new technical concept for power systems, and it is important to precisely delineate this concept for actual applications. As a critical infrastructure, power systems have to be prepared to survive rare but extreme incidents (natural catastrophes, extreme weather events, physical/cyber-attacks, equipment failure cascades, etc.) to guarantee power supply to the electricity-dependent economy and society. Thus, resilience needs to be integrated into planning and operational assessment to design and operate adequately resilient power systems. Quantification of resilience as a key performance indicator is important, together with costs and reliability. Quantification can analyze existing power systems and identify resilience improvements in future power systems. Given that a 100% resilient system is not economic (or even technically achievable), the degree of resilience should be transparent and comprehensible. Several gaps are identified to indicate further needs for research and development.ISSN:0885-8950ISSN:1558-067
