EDITORIAL

Dear Reader, 

At R&D Nester, our motto is "Creating a Smart Energy Future"!

This issue of our Newsletter is a good example of walking the talk. Indeed we are bringing to you six recent direct

contributions from our side, in the form of papers and scientific contributions, on very different energy system aspects.

One of them, in the field of network planning, is the recent publication in the ENERGIES journal entitled "The Innovative FlexPlan Grid-Planning Methodology: How Storage and Flexible Resources Could Help in De-Bottlenecking the European System".

Still in the planning field, but applied to offshore wind energy, there is the paper entitled "Grid capacity for floating offshore wind integration - The Portuguese Case" published in the International Conference on Renewable Energies Offshore, RENEW 2020.

Another one addresses energy forecasting that was the subject of the paper presented in the IEEE PES Innovative Smart Grid Technologies (ISGT) Europe Conference entitled "Energy forecasting using an ensemble of machine learning methods trained only with electricity data". Still in this event we presented a poster on "Impact of the dynamic line rating analysis in regions with high levels of wind and solar PV generation". These addressed both forecasting of generation and forecasting of consumption/load.

Moving away from planning and forecasting, we highlight our contributions as speakers to the flexibility topic with the webinar on the International Smart Grid Action Network ISGAN entitled "Flexibility needs at system level". There is also an expansion on this topic in the section below on Technical Information.

Finally, two additional contributions are in the field of digitalization and substations: one is our paper at the CIGRE Regional South-East European Conference RSEEC 2020 entitled "Digital substation testing with HIL Implementation of process bus and Line protection over MPLS" and another one is the publication in the PAC World Magazine "From Specification to the Substation - The OSMOSE Project Contribution to improve the IEC 61850 Engineering Process".

Additionally to these contributions we continue to work towards new contributions. Examples of this are the recent kickoffs of two additional projects: "MarCo - Research on Key Technologies of the European electricity market coupling" and "OneNET - TSO - DSO - Consumer: Large-scale demonstration of innovative grid services through DR, storage and small-scale (RES) generation". Read more about these below.

Don't forget to test your knowledge on energy trivia with our Quiz below and to follow us on our LinkedIn page (https://www.linkedin.com/company/r&d-nester), where these and other updates are often highlighted.

Enjoy your reading and please continue to share with us your feedback!

R&D Nester’s new Project on the European Electricity Market Coupling

R&D Nester started the project MarCo - Research on Key Technologies of the European Electricity Market Coupling in November 2020.


The European electricity market coupling is the process of building the internal European market for electricity. The realization of the internal European market for electricity increases the security of electricity supply in Europe, promotes Europe's energy independence and has the potential to lower greenhouse gas emissions and the price of electricity, allowing widespread consumption of renewable generation, even in regions without significant renewable resources.

This project has a duration of 21 months and studies the development of the internal European market for electricity, its operation and the coordination and negotiation mechanisms supporting the SDAC (Single Day-Ahead Coupling) and the SDIC (Single Intraday Coupling).

MarCo performs an analysis of the existing mechanisms and the trends of future developments, including those aspects related to the allocation of capacity between bidding zones and the congestion management. To this end, the project will develop a market model with security constraints and chronological stochastic simulations to support the quantitative assessment of the efficiency of the processes in the SDAC and the SDIC, in order to identify opportunities for improvement in the construction of the European internal electricity market.

TECHNICAL INFORMATION

Flexibility providers: identification and cost evolution

The current fast changing context of power systems presents multiple challenges for grid planning studies. The need for flexibility in the system needs to be addressed through flexibility solutions. Although there is no unified and agreed definition for the term 'flexibility' in power systems, one common definition by IEA is [1]: "the ability of a power system to reliably and cost effectively manage the variability and uncertainty of demand and supply across all relevant timescales, from ensuring instantaneous stability of the power system to supporting long-term security of supply". 


Flexibility resources can be used to provide the required flexibility services for a reliable and secure operation of the power system. In the last edition of our newsletter, we dedicated a section to the identification of energy storage systems (ESS) which are examples of flexibility resources. Herein we further identify additional flexibility resources and provide a tentative characterization of those, focusing on the envisaged application and providing some tentative cost characterization.


In grid planning studies, one needs to take into consideration the power and energy capacities. From a grid planning perspective, power capacity relates to the ability of meeting peak demand with the net generation, allowing not to oversize the network to answer to peak demands and support the fluctuations in RES generation and demand variation. On the other hand, energy capacity is related to the duration in which the resource can provide a flexibility service at the desired power rate. Table 1 includes a description of different flexibility resources and an expected range of power and energy capacities. Flexibility solutions for fast transient phenomena, with a large power capacity but low energy capacity (less than one hour) are not considered.


The deployment of these solutions is related to their economic viability assessment as they all present valid technical solutions, depending on the grid size and foreseen application. To give a general overview of the cost structure for these technologies, Table 2 contains the CAPEX and OPEX costs for the different technologies considering two time horizons: 2021, and 2050. Values are calculated assuming a discount rate of 6% per year [8].


As can be seen, significant price reductions are expected over the next years, indicating the need for new flexibility resources, enabling new flexibility services, and bringing technologies that are currently not economic viable to the market. Depending on the grid characteristics and operation conditions (e.g. share of renewables), a different set of these flexibility resources can be combined to achieve the best technical solution. Grid planning studies should also consider these resources as part of the grid expansion process, depending on the needs. A thorough analysis is performed in the scope of FlexPlan project, available in [9].

LITERATURE REVIEW

R&D Nester publishes scientific paper in Energies Journal related to work performed in FLEXPLAN Project about Grid-Planning Methodology

R&D NESTER is one of the partners involved in the publication of a new scientific paper in ENERGIES journalThe paper, entitled "The Innovative FlexPlan Grid-Planning Methodology: How Storage and Flexible Resources Could Help in De-Bottlenecking the European System" has as the objective of giving a general overview of the methodologies used in the project, as well as presenting the study cases considered.

FlexPlan aims to create an innovative grid-planning tool that allows including flexibility sources as alternatives to traditional grid reinforcement measures, applicable to transmission and distribution grids. The expansion candidates are evaluated in a multi-period timeframe (2030, 2040 and 2050) and selected through a multi-objective cost benefit analysis. The tool also considers the utilization of stochastic contingency analysis methods and considers as well the variability of renewable sources through a multi scenario analysis, including Monte Carlo variants. Simulated network models correspond to six regional cases covering a large part of Europe, allowing to demonstrate the tool capabilities in real cases of relevant size and complexity.

R&D NESTER contributed to the creation and publication of the paper by performing a summary description of the methodology used to create the network models and energy scenarios to be simulated in the regional use cases, as well as identifying all necessary data to the execution of these simulations. This work is developed by R&D NESTER as leader of Work Package 5, which is dedicated to the simulation of the project regional cases.

FlexPlan project is financed by H2020 and is developed in a consortium composed of 13 partners, including three TSOs and one DSO. R&D NESTER and REN are active members of this consortium.

World Energy Trilemma Index 2020 Report – Oct/2020

The World Energy Council's definition of energy sustainability is based on three core dimensions: Energy Security, Energy Equity, and Environmental Sustainability of Energy Systems.


Balancing these three goals constitutes a ‘Trilemma' and balanced systems enable prosperity and competitiveness of individual countries.


The World Energy Trilemma Index has been prepared annually since 2010 by the World Energy Council in partnership with global consultancy Oliver Wyman, along with Marsh & McLennan Advantage of its parent Marsh & McLennan Companies. It presents a comparative ranking of 128 countries' energy systems. It provides an assessment of a country's energy system performance, reflecting balance and robustness in the three Trilemma dimensions. 


Since 2010, the Report has provided an independent and objective rating of a country's energy policy and performance using verified global and country-specific data to assess management of three core dimensions: Energy Security, Energy Equity and Environmental Sustainability.


The World Energy Trilemma Index enables countries to keep track of their own progress and to learn with and from each other about what's working and what's not.


The annual assessment is designed as a tool to be used, not a report to be read and placed on a shelf. In this report we also suggest ‘how to' use the World Energy Trilemma Index as an energy policy pathfinding tool.
