Within the second period of TotalFlex, the work in WP1 has been focused on completing the infrastructure roadmap (attached). Also, work has been done on establishing an international link to the Arrowhead Artemis project. This link will further strengthen the demonstration activities of the totalFlex project and involved primarily WP1, WP2, WP5,WP6 and WP9. Work on the metering service and the notion of device abstraction is being continued.

Work package 2:

Leader:

The purpose of Work Package 2 is to use the data made available in WP1 for automatically detecting and predicting energy consumption, production and flexibility at a highly detailed level; that is, at the level of individual devices.

Consumption will stem from typical household devices and equipment, whereas production will focus on typical production units in households, such as solar power cells.

Data on consumption and production will then be used to automatically generating (potential) flex offers for the flexible part of energy consumption and production.

This will be done by employing data mining and machine learning techniques on data while at the same time taking the consumption context and historical behaviour of the users into consideration.

Work package 3:

 Leader:

The purpose of Work Package 3 is to develop a comprehensive business-intelligence solution for use in Work Packages 4, 5 and 6.

The solution will enable efficient aggregation of all kinds of data, including meter data, consumption and production, flex offers, prices etc., at all levels of detail.

The solution will also render possible complex analyses combining multiple perspectives/dimensions, including device, customer, market, system, distribution network, CVPP and TVPP. This will enable eg., analysis of whether the set timetables will cause problems in the shape of bottlenecks in the distribution network.

HCI

Contemporary private household electricity consumption is characterized by habits and routine and changing electricity consumption behaviour has proven very difficult and challenging. With future development of electricity production, e.g. more wind and solar power, and growing demand in private household consumption, e.g. charging electrical cars, more flexible ways of consuming electricity is needed and required. However, little effort has been put into to understanding what consumption can be made flexible and how this can be supported. The aim of Work Package 4 in TotalFlex is to investigate opportunities and limitations for flexible power consumption in private households. This will involve studies of private Danish households with a particular focus on identification and categorization of consumption that can be made flexible and consequently how such flexibility can be supported by and through technology.

Electric Power Systems

Contemporary distribution networks are characterized by radial and asymmetrical topologies incorporating a lot of installed and upcoming controllable electrical loads/generation units as well as a redundancy of measurements. However, their excessive extend obscures a direct individual online supervision and control at component level. Therefore, the aim of Work Package 5 of Totalflex is to investigate the possibility of creating simplified and adaptive grid load models to substitute or augment the conventional steady state analysis techniques. This will facilitate managing congestions online and hence determine the feasible transferable power within the distribution grid. The latter is of major importance in case of designing a smart grid market as it will eventually be necessary to put a "usage cost" to expected problematic areas in order to constantly fulfill the capacity limits of the grid components. These functionalities will later be integrated resulting in a technical virtual power plant capable of solving any grid related steady state operation issues.

Work package 6:

 Leader:

The aim of WP6 is to develop a Commercial Virtual Power Plant (CVPP). The CVPP is an IT tool which will keep track of flexibility from all connected devices. This means that the CVPP handles data inputs from the households delivering the flexibility. These flex-offers are continuously aggregated and provide the link between DER and the market developed in WP7. Agreements are made with the households regarding the flexibility and rewards linked to the flexibility.

When a macro flex-offer or part of is traded, the CVPP should be able to detect the physical geographical location of the micro-flex-offer and to activate the DER's delivering the service. This allows aggregated flex-offers to be displayed at various grid levels (low-, mid-, high voltage and transmission levels).

The CVPP is designed to handle the flex-offer commodities from the CVPP's to support all the needs of the different existing electricity markets. This includes day-ahead, intra-day, long-term contract based deliveries as well as a future prizing of grid constraints.

Design and development of a market for flexibility

The purpose of this work package is to design, develop and test electronic markets for trade with flexible electricity consumption. A good market will price flexibility correctly and ensure that households and SMEs will get the right incentives to market their flexibility. The market will thus help lower electricity consumption in peak load situations and ideally increase it when an excess of power produced by renewable resources is available. In this work package we define the "commodities" that will be traded in the market and analyse how supply and demand determine the price. We will then implement the pricing and allocation mechanisms and demonstrate how an electronic market can function.

Demonstration

The demonstration in TotalFlex consists of combined live demonstrations and simulation within the four main areas: Technical VPP (TVPP), Commercial VPP (CVPP), Detection and generation of flex offers as well as the market place.

Aggregation and automatic detection of flexible consumption will be performed from a number of houses equipped with smart-home equipment from Zense Technology, on the basis of which flex offers will be drawn up. In addition, we will show how flex offers can be automatically generated from a number of houses using heat pumps, where requirements for indoor climate comfort will be met. A running CVPP for the aggregation and dis-aggregation of flex offers will be demonstrated.

In terms of distribution, we will demonstrate a TVPP IT application for the modelling of low and medium voltage net. The TVPP can model the net in a manner that potential limitations will be made visible and can be predited and mapped for flex offers. Based on these prognoses, the net companies can use the market place to trade their way out of load problems.

The market place will be simulated and demonstrated, with flex offers as the focal point. At the market, the optimum price for flexible production and consumption per hour will be calculated, based on flex offers aggregated through a balance-responsible actor and flex offers from a net company needing to move consumption in specific time. Especially the connection to existing power markets is interesting.

Work package 9:

Leader:

The purpose of this work package is to influence and follow relevant standardisation work and secure that the design and realisation in TotalFlex is done taking relevant standards into acount. This work package is mainly a coordination activity with the purpose of securing a two way link between relevant standards and TotalFlex. This should secure that the TotalFlex work will leverage form work done within existing standards but also to feed the results into the ongoing standardization work done within the Danish S-557 group.

Work package 10:

Leader:

The project management task in TotalFlex is split between AAU CISS, who handles the administration, and Neogrid Technologies, who handles technical project managemet.

Project management can be divided into two parts, internal and external part.

Internal project management is to ensure coordination across the 9 work packages. Among other things, this means there will be a clear partitioning in TotalFlex among the work packages, so that the individual contributions can be combined at the end and the planned demonstration can be performed. It is also to be ensured that the individual interfaces are so well specified that it is possible to work independently on each work package.

External project management concers the communication and visibility of the results from the project (website, workshp, various papers from PhD students). In addition, the relationship with external partners must be cultivated, especially the inhabitants of the connected test houses. Finally, the external project management must ensure useful reporting.
