  • Thema: Microgrids, SG: Socio-technical Systems, SG: Markets
  • Subject: Field Test Microgrid with Focus on Convincing People to Use the System

1st of January 2016 the EcoGrid 2.0 project had upstart. In EcoGrid 2.0 the focus is different problem definitions for the future electricity system. The project is based on chosen partners and equipment from the original project. For further information click here.

ICT Implementation of the market concept

The bid-less, 5-minute market of EcoGrid EU:

  1. The price distribution component is designed as a combination of published subscribe and IP multicast technologies
  2. The Internet Service Providers (ISPs) of an area subscribe to the relevant price signals
  3. Within ISP domains, relevant price streams get multicasted
  4. The bid-less real-time market is (potentially) scalable to millions of customers

EcoGrid System Balancing

The overall conclusions of the EcoGrid EU evaluation team are:

  • A real-time price signal can be used to activate flexible consumption
  • There is a significant peak load reduction potential: The activation of flexible consumption with a five-minute real-time signal reduced the total peak load of the EcoGrid EU participants by approx. 670 kW or 1.2% of the peak load on Bornholm
  • The flexible  demand response can be forecasted – with some certainty – resulting in overall improved system efficiency
  • Households, having equipment that controlled their heating system to respond automatically to price signals, accounted for 87% of the peak load reduction
  • Involving the customers is the key to success. Personalised advice works best, but should be kept to a minimum due to the sheer volume in a national roll-out
  • Standardised 2nd generation smart grid equipment is necessary

Villa Smart

The EcoGrid EU test participants are invited to training sessions in Villa Smart. A communication and technical EcoGrid team in Oestkraft give individual advice regarding their particular role in the project and the new equipment.

The participants also have access to `My EcoGrid´ user portal on the web-site www.ecogridbornholm.dk.  At this portal the participants can find information about eg. actual prices and price prognosis for the coming hours.

EcoGrid – a New Real-time Market for Small-scale Electricity Consumers

The EcoGrid real-time market concept is an extension of the existing power balancing markets and control systems in Europe. A five-minutes real-time market will extend the market operation closer to real-time. It means that the problems with forecast errors, eg related to wind generation inherently present in the conventional markets are minimized.

The development of a real-time market is considered one of the most efficient ways to meet the challenges on operating a system with increasing shares of renewable sources.

The EcoGrid real-time market will increase demand-side market participation and thereby reduce the need for costly flexibility on the production side/or compensate for traditional balancing power and services from convec ntional generation displaced by generation based on renewable sources.

Advanced meters and ICT solutions will enable residential electricity consumers to offer TSO´s additional balancing service for the benefit of the individual customer and the society.

Demand-participation in the system-wide market for energy and balancing in the transmission network

The Bornholm Test Site

The EcoGrid EU concept will be demonstrated in a single full-scale demonstration in the complete Bornholm distribution system, owned and operated by the local DSO, Østkraft.

The Bornholm distribution system is part of the Nordic interconnected system and fully integrated in the power market “DK2”. It is located at the Danish island of Bornholm in the Baltic Sea.

The system comprise ~28.000 electricity customers (55 MW peak load) and has very high penetration of a variety of low-carbon energy resources, including wind power (30 MW), CHP (16 MW), active demand (under roll-out during the project), Photo Voltaic (1 MW under roll-out during the project) and electric vehicles (under roll-out during the project). Attempt is currently made to further increase the amount of renewable energy resources, especially wind power as well as storage. The distribution grid includes a meshed 60 kV network with 16 60/10 kV substations, 91 10 kV feeders and approximately 1000 10/0.4 substations.

Østkraft and the strategy for Bornholm

The Bornholm distribution grid is operated by the local DSO, Østkraft, which is owned by the Bornholm municipality. The Bornholm municipality has, together with local industry, public and other authorities, established the “Bright Green Island” strategy for Bornholm focusing on energy and environment with the goal to become 100 % based on renewable energy. In 2009 the share of wind power penetration in the Bornholm system was 40 %.

The EcoGrid EU Market Concept

The Ecogrid EU concept is aiming at improving the balancing mechanisms by introducing a 5 minutes real-time price response that will provide additional regulation power from smaller customers with both reducible demand and excessive load in periods.

The general concept of this proposal is based on a real-time market approach that lets destributed energy resources and flexible electricity demand receive and respond to variable electricity prices. Soon after clearing the electricity price from the already well established day-ahead Elspot market is sent to the end-user. This price acts as a forecast of the 5 minutes real-time price and allows scheduling of assets that require advance planning.

Price signal updates

In the course of the day the price signal is updated in real-time, i.e. every five minutes, to reflect the need for up or down regulation due to an imbalance in the power system. If no imbalance exists the real-time price will be equal to the day-ahead Elspot price. Sending a price update every five minutes makes is possible to take advantage of flexible electricity demand and distributed energy sources.

Market-based platform and ICT infrastructure

The concept provides a market-based platform and ICT infrastructure that extends the current electricity market to a shorter time horizon and to smaller assets. By letting DERs receive and respond to real-time prices it is ensured that DERs can be better utilized in the market and by using a simple and cost efficient market concept it is ensured that small-scale DERs can take part of the market. Both these factors therefore imply a large potential for improved system operation by utilizing resources that would otherwise have been left unused.

Villa Smart – The EcoGrid EU Test House

Villa Smart – The EcoGrid EU Test House Oestkraft, the local electricity company on Bornholm has established the “Villa Smart”.

It is a normal residential house equipped with Smart Grid solutions, ie. the EcoGrid installations.

The house will function as a showroom where the 1,900 participating test customers can learn how the EcoGrid EU project might impact the everyday life of a typical household.

The EcoGrid EU test participants have been invited to training sessions in Villa Smart. A communication and technical EcoGrid team in Oestkraft give individual advice regarding their particular role in the project and the new equipment.

The participants also have access to `My EcoGrid´ user portal on the web-site www.ecogridbornholm.dk.  At this portal the participants can find information about eg. actual prices and price prognosis for the coming hours.

EcoGrid EU meets the Wind Power Challenge

Local politicians, industry and residents on Bornholm want to find solutions for their actual wind power challenges that many other regions of Europe already experience or are expected to meet in the near future.

The test-site is located on the Danish island Bornholm where the share of wind power is 50 % of electricity consumption.  Here wind power supply already exceeds the entire demand for electricity in many hours the course of a year.

This situation is likely to appear more frequently – significantly increasing the need for power balancing resources not only on Bornholm and in Denmark, but in the rest of Europe.

Introduction of a real-time market can provide valuable balancing resources and ancillary services and contribute to reduce the costs of these resources. The EcoGrid EU real-time market has a very high time resolution (five minutes), which improves the capability to manage high amounts of rapidly fluctuating renewable energy sources, including wind power generation.
