Work Package 3 structure

Work Package  3.1: Improved system reliability and technical planning criteria  

 

Work Package 3.1 develops robust set of criteria for the planning of transmission systems in an international context, characterised by a liberalized environment and increasing penetration of renewable energy sources. The criteria will be suited to the European transmission network in order to define reinforcement and extension priorities according to the EU energy policy. Finally Work Package 3.1 provides valuable inputs for political, regulatory decision makers and network operators and to contribute to the harmonisation of pan-European approaches or infrastructure development.

 

Sub-Task 3.1.1: Review of existing methods for transmission planning and for grid connection of wind power plants 

 

Sub-Task 3.1.1 summarises existing studies and experiences of methods for transmission planning particularly in the EU countries.

 

Sub-Task 3.1.2: Extension of existing transmission planning methods

 

Sub-Task 3.1.2 expands the existing transmission planning methods introducing a probabilistic approach. This approach deals with increased uncertainty of power flows, introduced by the growth of distributed generation and renewables and takes in account many combinations of generation unit dispatch based on cost optimization. For each combination it determines the risk for line overloading and voltage constraints.

 

Sub-Task 3.1.3: Consultation of stakeholders on new transmission planning criteria 

 

In Sub-Task 3.1.3 the Transmission System Operator partners review and comment the draft report prepared by Sub-Task 3.1.1 and 3.1.2.
 

Work Package 3.2: Investments signals: a quantitative approach based on cross-border capacity allocation

Work Plan 3.2 develops tools to assess bottlenecks and investment issues for cross border capacities in the European electricity markets and flow-based coordinated auction model, for auctions of cross-border transmission capacity, as a quantitative approach to derive investment signals. Then it applies the model to a significant part of the UCTE transmission systems making load-flow calculations for different time horizons based on long term scenarios. Finally it evaluates investment projects and analyses different long term investments.

Sub-task 3.2.1: Assessing status of EU-grid congestion

Sub-Task  3.2.1 applies the model ELMOD (load flow based model of electricity markets)developed by TUD to the European electricity market for the time frames 2010, 2012 and 2015 in order to consider different congestion management method for each EU Country.

Sub-task 3.2.2: Model-based elaboration of market area prices for different hubs and time horizons

Sub-Task  3.2.2 analyses the impact in grid investments on tie-lines, for instance on prices, and provides fundamental insights for policy implications regarding incentives in cross-border transmission investments.

Sub-task 3.2.3: Development of grid models and preparation of Power Transfer Distribution Factor matrices

 

Sub-Task  3.2.3 develops grid model for different time horizons; makes load flow calculations based on inputs (investments) from Work Package 2 and, basing on Load Flow results, calculates PTDF matrices.

Sub-task 3.2.4: Development and application of a coordinated auction model covering a significant part of the UCTE interconnected system

Sub-task 3.2.4 develops a coordinated auction model (covering the South Eastern Europe countries, former CENTREL countries and Germany); verifies the opportunity to extend the model to the neighbouring regions(e.g. Italy, Benelux, France and Switzerland) and eventually extends it and analyses different results regarding their use as economical input (investment signals) for transmission expansions.

Work Package  3.3: Implementation of a comprehensive framework to assess technical-economic and strategic benefits of transmission expansion

Work Package 3.3 defines possible criteria to be used for the quantification of benefits given by the development of power transmission infrastructure; prepares a set of information about cost of recently-developed transmission infrastructures, and develops a tool for the quantitative assessment of benefits given by the development of power transmission infrastructure.

Sub-Task 3.3.1: Definition of possible criteria to be considered for the quantification of benefits given by the development of power transmission infrastructure

Sub-Task 3.3.1 gives a spectrum of benefits which can be given by infrastructure development and by reinforced system interconnections illustrates  the methodologies and criteria for the assessment of benefits in terms of improved system reliability and benefits in terms of increased efficiency of power generation and increased competitiveness in electricity markets. It derives methodologies and criteria to assess benefits in terms of sustainability: (e.g. better exploitation of renewable resources characterised by largely intermittent production and reduction of emissions of power generation). Assesses methodologies and criteria to quantify benefits of improved interaction of transmission and distribution grids by means of a “smart” development of transmission and distribution infrastructures.

Sub-Task 3.3.2: Collection and preparation of a set of information about cost of transmission infrastructure

Sub-Task 3.3.2 develops a tool to assess benefits of new transmission projects that will be validated in Work Package 3.5 activities.

Work Package 3.4: Coordination of investments in gas and electricity infrastructures

Work Package 3.4: supports coordination of investments in gas and electricity infrastructures; develops a probabilistic coupled model of electricity and gas infrastructures and validates the model and the tool and to apply them to identify weak points in the existing electricity and gas infrastructures in continental Europe.

Work Package 3.5: Application of the framework to assess technical-economic and strategic benefits of specific projects 

Work Package 3.5 applies to develop the tool develop in WP 3.3 on real-life case studies (9 electricity projects which have been declared of European interest by the European Commission) in order both to validate the tool and to understand the possible impact of the proposed approach.

Sub-Task 3.5.1: Definition of case studies to be investigated and collection of relevant information

The case study develops a suitable detailed modelling of the power grid. ST 3.5.1 also provides estimated costs/investments for the projects under analysis. A note on results of this sub-task and inputs to other ones is prepared.

Sub-Task 3.5.2: Preparation and modelling

In Sub-Task 3.5.2 the information collected in sub-task 3.5.1 are implemented in model-formatted inputs.

Sub-Task 3.5.3: Simulations

In Sub-Task 3.5.2 the framework will be applied in order to analyse case studies defined in sub-task 3.5.1. The report on simulations results that includes the note prepared within sub-task 3.5.1 will be drafted.

Sub-Task 3.5.4: Preparation of WP3 report and of documents for consultation of stakeholders

The final report will cover all the activities carried out within WP3, summarising the outcomes of the first “technical” work packages (WP3.1, WP3.2, WP3.3 and WP3.4) and of the “implementation” work packages (WP3.5, WP3.6 and WP3.7). Finally, the technical documents for the workshop of WP3 will be prepared.

Work Package 3.6: Incentives and regulation to support transmission investments

Work Package 3.6 analyses the impact of regulation and incentive mechanisms on transmission investment so as to improve the capacity of TSOs to efficiently address the challenges related to interconnection development, demand growth, and more efficient system integration of renewable energy sources.

Sub-Task 3.6.1: Investment needs and scenarios 

Sub-Task 3.6.1 gathers the main conclusions of the other work packages and studies performed for the EC to identify the possible paths to the future problems on the European network and Investment needs.

Sub-Task 3.6.2: Review of existing incentive schemes and regulation framework for transmission development

The objective of Sub-Task 3.6.2 is to assess the different parameters at stake regarding the promotion in Europe of investment in transmission assets. In the first part these parameters will be reviewed and discussed. In the second part, the regulatory framework of few  EU Member States will be compared and a quantitative analysis of investment
trends will be carried out .In a third part, stakeholders (transmission system operators and regulators) will be consulted to study how the different mechanisms impact TSOs behaviour and to estimate the efficiency of the different options.

Sub-Task 3.6.3: Investments for an efficient integration of renewable energy sources (RES)

Sub-Task 3.6.3 analyses how to increase the electricity generation from RES by improving its integration in transmission and distribution systems. Moreover this task studies the impact of Distributed Generation /RES regulation on distribution systems and transmission systems to address the way transmission systems should be adapted both in terms of investment and regulation. The links between RES promotion and wholesale markets will also be analysed).

Sub-Task 3.6.4: Transmission investment and regulation: trade-offs and improvements

Sub-Task 3.6.4 provides a broad analysis of investment issues in transmission addressing  economic and political dimensions such as the economic status of networks and its impact on incentive mechanisms and the impact of congestions and on production investment; the role of market mechanisms, incentives, investment signals and the need for long term planning. ST 3.6.4 addresses the trade-offs between incentives and constraints to optimise the development of transmission systems coherently with the energy policy objectives of the EU. A set of policy recommendations is proposed.

Work Package 3.7: Consensus on new transmission infrastructures

Work Package 3.7 contributes to the objective of the European Commission to set up national procedures under which planning and approval processes for infrastructure projects should be completed in a maximum time span of five years.

Sub-Task 3.7.1: Review of existing methods of transmission system development planning and approval procedures and international cooperation

Sub-Task 3.7.1 reviews existing methods adopted in Europe to overcome the barriers to transmission system development. To this aim, real case studies, based on the experience of TSO partners, will be analysed to identify the main strengths and weaknesses of the best practices selected from the current approaches.

Sub-Task 3.7.2: An innovative approach based on the assessment of transmission project benefits to improve consensus on new infrastructures

Sub-Task 3.7.2 develops an innovative approach of transmission project benefits should clearly assesses and states costs and benefits of the project for each stakeholder. The costs and benefits considered are economical, environmental and related to the security of supply. With this innovative  approach trade-offs can be made and well informed decisions are taken, balancing the costs and benefits between all stakeholders. The aim of the sub-task is to make, in a clear and quantitative way, an inventory of  opportunities for and threats to all relevant stakeholders for specific priority projects assessed in Work Package 3.4 of this proposal, as well as to quantify total (societal) costs and benefits.
