Title : Voltage quality monitoring, dips classification and responsibility sharing

Convener : Jorge Esteves, ERSE - Portuguese Energy Services Regulatory Authority; Portugal

Scope : The European energy regulators (CEER) and the association of the electricity industry in Europe (EURELECTRIC) have for some years a cooperative work in the field of quality of electricity supply, involving joint meetings and the participation of regulators at the dedicated CENELEC Technical Committee. A major Workshop on "Voltage Quality Monitoring" was organised jointly by the two organisations during November 2009, in Brussels, involving more than 80 participants and achieving very important conclusions about the importance of this topic. In parallel, one of the changes agreed at CENELEC level for the EN 50160 standard revision is a comprehensive and effective treatment of voltage dips classification, including reference to standards (e.g. EN 61000-4-11) for testing of equipment against voltage disturbances and to the electromagnetic environment classes defined by the EN 61000-2-4. This reference can be seen as an important pre-condition to responsibility sharing between the stakeholders, as follows:

• good voltage quality at the customer's bus is the network operator responsibility; • good quality for load current drawn from the bus is the customer's responsibility; • developing and supplying equipment with adequate tolerance to power quality and cost-effective power conditioning devices with appropriate technology are the manufacturers' responsibility; • ensuring an efficient balance of these responsibilities is the role of the National Regulatory Authorities. The implementation of a standardised voltage dips classification, the monitoring, the collecting and publicising of reliable data about the real situation in each European country, will allow an understanding and benchmarking of the real situation together with the impacts for networks and customers.

This CIRED 2011 round table, jointly organised by CEER and EURELECTRIC, envisages emphasising the importance of these advances and to widespread the good practices already in place. Panelists :

- Karstein Brekke, CEER Electricity Quality of Supply and Smart Grids TF ; NVE - Norwegian Water Resources and Energy Directorate , Norway - Kevin Niall, EURELECTRIC Standardisation Group; Manager, Network Strategy, ESB Networks, Ireland - Maurizio Delfanti, CENELEC TC 8X/WG1 Secretary;Energy Dept., Politecnico di Milano, Italy - Math Bollen, EI - Swedish Energy Markets Inspectorate, Sweden RT2b

June 7, 11.00 hrs - 12.30 hrs

Title : Economic framework of power quality

Convener : Jose Luis Gutierrez Iglesias, UNESA, Spanish Electricity Industry Association, Spain

Scope : Improving power quality in electrical systems can result in significant savings and can be a competitive advantage. It is important for customers and suppliers to work together in identifying the best alternative for achieving required level of performance.

Various independent studies have been undertaken by power companies, consultants, regulators, and research organizations to estimate the cost of power quality problems to the power companies and their customers Deregulation and industry restructuring are placing utilities under increasing pressure to both improve customer reliability and decrease cost.

Investment and economic losses depend on numerous parameters, and this is itself an ambiguity and complexity factor in comparison issues regarding power quality improvement projects. Calculation of financial damages related to system quality problems widely various from customers and facility managers prospective.

Title : EMF - Revision of magnetic fields limits

Convener : Herwig Renner, Technische Universität Graz, Austria

Scope : After several months ICNIRP finalized in summer 2010 new guidelines for limiting EMF exposure which were finally published in late autumn. Compared to existing guidelines, published in 1998 especially in respect to harmonics the new guidelines are less conservative. Based on new results from exposure simulation using FEM the reference value for the magnetic flux density (general public, 50 Hz) now increased to 200 µT instead of 100 µT given by guidelines 1998.

• ICNIRP 10 - changes & consequences for grid operators and industry • Protection of employees: Directive 2004/40/EC • ELF EMF Standardization (CENELEC, IEC) - ongoing work; lack of knowledge • Practice of assessment in case of non-sinusoidal exposure - are instruments ready for given requirements?

Title: Unlocking Demand Contribution to Distribution Network Management-Energy efficiency, Smart Metering for Smart Grid, Industrial and Commercial demand response

Convener : Goran Strbac, Imperial College (UK)

Scope : One of the key concerns with the future low carbon electricity system is that it may be characterised by much lower generation and network asset utilisations given a significant penetration of low capacity value renewable generation (e.g. PV and wind) combined with a potential increase in peak demand that is disproportionately higher than the increase in energy, driven by expected electrification of heat and transport sectors. In this context, demand side participation could facilitate increase in both generation and network infrastructure utilization, deliver an increase in efficiency of system operation and hence support a cost effective evolution to a low carbon future. This Round Table will discuss experiences from actual applications of various forms of demand response covering commercial and industrial applications but also the potential in domestic sector enabled by smart metering system supported by an appropriate information, communication and control infrastructure. Consequences for future distribution network operation and planning caused by the shift from a passive to an active philosophy of network control will also be discussed.

Title : Experiences form Major Smart Grid Demonstrators

Convener : Dave Openshaw, UK Power Networks (United Kingdom)

Scope : Application of Smart Grid concepts and technologies will be critical for facilitating radical transformation of distribution network operation and planning philosophy to support transition to low carbon future. Distribution networks will need increase capacity to connect more renewable generation to the network, make use of flexible demand arising from smart meters and intelligent white goods, through using both direct control and innovative time of use tariffs etc. In this context, there have recently been a very significant interest in demonstrating, at a large scale, alternative smart grid technologies for a variety of applications ranging from enhancing generation system operation through real time energy balancing to managing power flows and voltage profile in local distribution networks. This Round Table will discuss experiences from several major Smart Grid demonstrators including comparisons of objectives, scope, strategies and approaches adopted, parties involved etc, also covering practical experiences of developing actual large scale demonstrators and discussing lessons learned.

June 8, 11.00 hrs - 12.30 hrs

Title : Planning the distribution system development with a proper coordination of TSO and DSO

Convener : Riccardo Lama, ENEL Distribuzione spa (Italy)

Scope : Traditionally, distribution network planning has been developed with minimum interaction with transmission network condition and phenomena, as well as transmission network has been planned with minimum reference with the development process occurring at DNO level.

This was, and still is, largely justified, not only because a joint systematic planning would imply complex calculation whose computability has not been easy since a few years ago, but also because in most cases the two processes are indeed independent in practical terms.

Nevertheless, there are more and more cases in which a joint planning process or a systematic information exchange proves itself convenient or even necessary.

The round table is meant to share experiences among network operators (TSOs and DSOs) about the opportunities and needs in terms of joint network planning.
