2 TERMINOLOGY PQM Acronym for Power Quality Management in the context of the project comprising both reliability management and voltage quality management AMS Acronym for Advanced Metering and Control Systems including smart metering, two-way communication etc. Quality of the electricity supply (QoS) collective effect of all aspects of performance in the supply of electricity NOTE This includes security of supply as a prerequisite, and also reliability, power quality, pricing and customer relationships. Reliability (of an electric power system) probability of satisfactory operation of a power system over the long run. It denotes the ability to supply adequate electric service on a nearly continuous basis with few interruptions over an extended period of time NOTE Reliability is the overall objective in electric power system design and operation. Voltage quality = power quality characteristics of the electric voltage at a given point on an electric power system, evaluated against a set of reference technical parameters NOTE These parameters might, in some cases, relate to the compatibility between electricity supplied on an electric power system and the loads connected to that electric power system

13 APPENDIX I ORIGINAL PROJECT APPLICATION
14 A NEW CONCEPT FOR POWER QUALITY AND RELIABILITY MEASUREMENT AND MANAGEMENT THE PQM PROJECT Project description PART 1: The PQM project 1. Objectives The project has two main objectives one from an industrial and new services perspective and one from a community/utility perspective: Industrial and service perspective Community/utility perspective Objectives To develop new products (new instruments new software) and services for power quality measurement and management for the national market based on a new measurement patent held by SINTEF Energy Research Partial goals Detailed design and production of a 0- series (50 units) of a new low cost PQ measurement instrument (SINTEF Energy Research patent) Development of PQ measurement instrument local software Deployment of the 50 units in typical supply situations Development of PQ measurement repository (PQ database) Measurement concept testing and verification (in situ tests) Create a platform for industrialization of the new measurement and service concept To develop and evaluate a new concept for quality of supply management in electrical power systems including power systems with an influx of distributed generation, including measurement documentation, estimation, of quality of supply parameters related to power system reliability and power system quality (voltage quality) to achieve the best balance between costs and quality. Develop a new holistic concept for quality of supply management, leading to enhance present quality of supply documentation and measurement processes Develop tools and methods to manage and interpret large amounts of PQ data to determine trends and make them fit for PQ problems alleviation and decision support purposes. Development of adequate models for simulation and prediction of relevant quality of supply indices in T&D systems - based on T&D system models, historic PQ measurement and fault and interruption statistics To contribute to PQ analysis of T&D systems with influx of distributed generation and renewables To contribute to improvement of the quality of supply regulatory framework Competence building through PhDcandidate in the field of quality of supply simulation or power quality measurement, diagnosis and signal analysis.
15 In meeting the above mentioned objectives and partial goals, the project will provide the different stakeholders (customers incl. producers, DSOs, TSOs, regulators and manufacturers of equipment) with a knowledge base and necessary measurement, documentation and decision tools to achieve the best possible balance between costs and quality. 2. Frontiers of knowledge and technology The motivation for the PQM project is both linked to state of the art concerning technology, knowledge, impact of DG and to the changes in regulatory frameworks nationally and internationally: Quality of supply problems in T&D systems increase both due to increased pollution in networks (increased emission) and due to increased use of electrical equipment that are sensitive to disturbances (reduced immunity) Customers quality of supply requirements with respect to reliability and voltage quality increase as electricity is more widely used in business critical work and industrial processes The increased influx of distributed generation (i.e. small hydro power, small wind farms) and renewable technologies (for instance larger wind farms) in T&D systems is restricted by power quality and reliability aspects, giving new challenges both to grid operators (TSOs and DNOs) and to power plant operators Trend towards increased customer protection in general both at the national and international arena (EU) and more strict quality of supply legislation (for instance the new Norwegian PQ Code, the work for Council of European Energy Regulators) Lack of knowledge on how to achieve the best balance between quality of supply and costs (methodology, decision tools) Lack of knowledge on how to optimally share responsibilities between quality of supply stakeholders Limited observation of quality of supply delivered to customers due to expensive measurement equipment. An expected substantial growth in PQ data (reliability data, voltage quality data) to be managed by utilties steming from new meters two way communication schemes etc. A important motivation for the project is also a novel LV measurement instrument patented by SINTEF Energy Research which is expected to have a production cost far less than measurement equipment available in the market today less than 1/10 of what is presently available in the Norwegian market (typically costs to day range from 1000 per instrument). The instrument is a single phase instrument which can measure the following voltage phenomena: Frequency, magnitude of the supply voltage, supply voltage variations, rapid voltage changes - flicker, supply voltage dips, interruptions, overvoltages and harmonics. The main tool applied for management of quality of supply has been to establish technical limits for emission of disturbances from electrical equipment and plants and immunity limits for disturbance levels that equipment should withstand. These limits are used as a basis for solving power quality problems and for settling disputes between involved parties. And they might be referred to in legal documents. By respecting certain planning limits the utilities estimates power quality problems to be limited as a proactive measure. But PQ problems when they appear are often solved by a limited number of experts limitations that has lead to unnecessary delays in the problem solving process and major malfunction and damages on electrical equipment and plants.
16 Some phenomena such as interruptions and voltage dips do not have international recognized limits they are treated on an incentive basis with penalty schemes such as the Norwegian CENS arrangement (Cost for Energy Not Supplied). The situation now calls for a much more holistic approach by all parties involved in the quality of supply field and a much closer coordination between technical power quality levels and costs and hence new tools for documentation and management a vision that is signalled in the new Norwegian PQ Code. New distributed generation sources influence the voltage quality and dynamics of distribution networks in a negative way, and introduce a need for detailed computer-based analyses to determine this influence based on size, placement, technology and characteristics of the generation unit (as short circuit contribution, inertia, control equipment, etc.). Such detailed analyses are both time-consuming and costly and the detailed data needed are very often not available. Therefore guidelines are needed to determine whether such analyses are needed or not, with reference to accepted voltage quality rules and regulations. A synthesis of the main shortcomings in today s measurement and management of quality of supply is the lack of quality of supply measurement and documentation at the customer s supply terminals, and hence the utilisation of such information in stakeholders work, PQ problem solving and PQ decision processes. The project is expected to reduce those shortcomings. The frontier of knowledge and technology offers many building blocks for a more holistic quality of supply management value chain. There is however a need to develop the overall PQ value chain, the missing building blocks and to verify the functionality of the different elements. 3.

Some of these are research tasks labelled (R) while other are activities are more administrative or spin-off activities related to the research activities labelled (A).

Project organisation and management Project Management: SINTEF Energy Research will have the project leadership through the overall Project Manager (Dr. Kjell Sand). Advisory Council: The project partners (DNOs, TSO, subcontractors, Norwegian Electricity Industry Association) will form an Advisory Council meeting twice a year. The project partners are: Hafslund Nett, Statnett, Norsk Hydro, Helgeland Kraftlag, Lyse Nett, EBL, Statkraft, Skagerak Nett, Powel The role of the DNOs and the TSO in the project is to initiate cases for the project to be tested in their local systems. The grids will be used as laboratories to perform real case testing and evaluations. EBL (Norwegian Electricity Industry Association) follows the project from and industry strategic position. Powels role in the project is to provide the software basis need in the project and to carry out software related support and services to the project. 6. International co-operation EdF R&D EdF R&D in France is planning to launch a project called METRIQUE - Measurement, Economical and Technical models Relative to Indicators for the QUality of Electricity. As the METRIQUE project has activities that are related to the PQM project, it has been agreed to coordinate the two projects as a joint venture to enhance project results in both projects (Letter of intent from EdF R&D is enclosed. As a part of this coordination, it is planned that the Ph.d. student should stay part time with EdF R&D a one year stay has been planned. The SINTEF Energy Research project OPAL Optimization of reliability in power systems will be completed in 2006. The project has an international user group from Norway, Sweden, Denmark and Finland. The OPAL project is expected to give valuable input to the PQM project, and hence a follow-up based on the the OPAL project involving the Nordic usergroup might be foreseen. It is also planned cooperation with Italian Regulatory Authority for Electricity and Gas (AEEG) who is conducting one of Europe s largest PQ measurement campaigns.. SINTEF Energy Research has in previous projects cooperated with AEEG in the Quality of Supply domain, and a meeting is planned in Milan in September to further decide cooperation principles.
