The project is divided into three main work packages, supported by a Management and dissemination WP
WP1 – Scenarios and use cases
Leader: ARMINES, partners involved: ARTELYS, HESPUL, MAIA EOLIS, FRAUNHOFER, INESC TEC
The objective of WP1 is to elaborate a set of scenarios to be used as inputs in the other work packages. Each scenario will be driven by a set of assumptions on e.g. level of fluctuating renewable energy in the mix, demand profile and its evolution over time, social acceptability, costs prediction. Each scenario will take the form of:
- A set of static data: production means and/or power conversion systems including their features and locations, a transmission network model and demand-related assumptions (demographics, overall national yearly consumptions, uses, …).
- A set of time-correlated hourly time series on each zone of the network model including demand and production over time, forecast errors, storage needs, and this for several different meteorological years.
- Definition of a network study case based on the portuguese electric power systems for future scenarios with a high share of renewables.
In WP1 we will propose a methodology that allows obtaining these data while ensuring that the corresponding system is i) feasible (constraints are respected) and ii) optimal (total system costs in CAPEX and OPEX are minimised). Additional analyses will include the determination of the demand for FCR, FRR and RR and the system’s ability to provide them. Finally, the impact of Dynamic Line Rating (DLR) on the continental network and its potential to increase its flexibility will be studied. Also, WP1 will take care of the definition of the use cases and the KPIs of the project which will then be used to evaluate the results of the demonstration and to compare them to the state of the art of similar european projects. For this reason WP1 is divided into two tasks, each one with its own deliverable: WP1.2 ‘Scenarios’ and WP1.1 ‘Use cases’.
WP2 – New services and actors in the electricity market for an improved electric system
Leader: INESC TEC, partners involved: ARTELYS, ARMINES, FRAUNHOFER
Also this WP is composed by two tasks: WP2.1 ‘New market tools’ and WP2.2 ‘Benefit from new actors for ancillary services provision’. The content of the two deliverables will be described below.
New market tools: The effect of the change in nature of the electricity mix on the volume and the stability of the different markets (long-term, day-ahead, intraday, balancing) needs to be studied with a detailed simulation of the market and its different actors. For this purpose, together with a market simulator, we will develop tools for the simulation of actors involvement and we will develop numerical algorithms to construct bidding strategies across several power markets taking into account uncertainty. A new market mechanism to allow the combined use of all the spatio-temporal information offered by all the measured renewable energy sources production will be proposed and its advantage in term of forecast error reduction will be demonstrated. Finally this work will allow to give insights and recommendations in term of market design, since it will be possible to launch the developed tools for different market configurations.
Benefit from new actors for ancillary services provision: Following the VPP optimization function that supports the participation in the electricity market, a real-time coordination function is necessary to ensure that the DER composing the VPP follow, with high accuracy, the AGC signal provided by the TSO and the reserve capacity offered in the market is fully available. This involves the following steps: (1) development and test of dynamic models for the DER forming the VPP in order to capture the dynamic response of each resource to an AGC signal in a seconds-to-seconds time scale; (2) calculation of an economic merit-order based on the operational cost of each DER (e.g., combination of depreciation, degradation and maintenance costs); (3) calculation of AGC related participation factors for each DER taking into account its dynamic response characteristics and the economic merit order.
WP3 – Demonstration
Leader: FRAUNHOFER, partners involved: FRAUNHOFER, ENERCON, INESC TEC, MAIA EOLIS
This is probably the most important part of the project and this WP will be divided into three main tasks: WP3.1 ‘Development’, WP3.2 ‘Experimentation’ and WP3.3 ‘Evaluation’. Each task will be completed by a deliverable describing the progress and the results. The repartition of the work among the tasks can be found below. In the first phase, ‘Development’, each partner will put in place the infrastructure necessary in order to carry out the experimentation. The development and adaptation of the necessary tools (software, ICT…) and the work to obtain the necessary authorisations for the experimentations are also carried out within the framework of this task. In parallel the control strategies previously developed for VPP´s DER integration in AGC systems as well the procedure for the derivation of dynamic equivalents for active distribution networks will be extensively tested and validated in a reduced scale laboratorial grid at INESC TEC that is to be integrated with a Power Hardware in the Loop (PHIL) platform. In the second phase, ‘Experimentation’ the use cases defined in WP1.1 will be tested for a statistically meaningful number of times on the test sites identified by the partners. In the third phase ‘Evaluation’ the results of the experimentation will be evaluated according to the KPIs identified in WP1.1.
WP4 – Management and Dissemination
Leader: ARMINES, Partners involved: ALL
This work package is divided in two parts: WP4.1 ‘Supervision’ and WP4.2 ‘Dissemination’. Regarding the first, the structure of the project management structure has been presented in Section 7.3. Here it is possible to add that this task will involve all the partners and that it is here that will be followed the work of the different national consortia in the reporting with their national funding bodies and with the ERA NET Smart Grid Plus community, with the work relative to ‘Task 3 Deliverables to the ERA-Net Smart Grids Plus initiative’ of the ‘Knowledge Community Standard Work Package’.
Regarding the second task, it will take care of all the aspects of dissemination relative to the ‘Knowledge Community Standard Work Package’, such as ‘Task 1. Involvement in formative evaluation’ and ‘Task 2. Crosscutting Knowledge Community activities’. Here will be also supervised other traditional dissemination activities such as the development of a website for the project and the presentation of the results to the Renewable Energy and Smart Grid community in conferences, workshops or through the specialised press.
