Theme 1: Integrating New Flexibility Tools and Principles for Planning

Technical Committee: Jan Desmet (Belgium); Ben Gemsjaeger (Germany)

As the ongoing transformation of energy systems leads towards a more diverse and dynamic energy landscape, planning future distribution systems that comply with the known objectives (efficiency, reliability, sustainability) becomes more and more complex and challenging. Existing planning principles need to be reviewed and may be adapted to consider the changing landscape and new technologies: Variable pricing strategies could provide different ancillary services, storage systems could be used to control frequency and direct peak shaving. In parallel innovative planning tools can utilise the increasing flexibility and digitalisation to cope with the planning insecurity and ensure highest efficiency.

Theme 2: Opportunities and Challenges with Operation Using Flexibility

Technical Committee: Carsten Boese (Germany); Ignaz Huebl (Austria)
The increase of new kind of loads (electric vehicles, battery storage) and the increase of overall electrical energy consumption with higher peak load has to be covered by new flexible operation functions. Any new and more flexible operation including a higher degree in automation will lead to opportunities in operating power systems more efficient. On the other hand side the digitalisation and increasing utilisation might be a risk in operating distribution grids. Due to cost-pressure also new methods to organise daily work are needed. Topic 2 covers all kind of using flexibility in operation as well as new methods to enable a higher degree in flexibility, showing opportunities and challenges and covering the entire power system.
Aspects are:

Theme 3: Flexibility Platforms and the Role of Future DSO's

Technical Committee: Dag Eirik Nordgård (Norway)
The evolution of the distribution networks through increased electrification and new load and generation technologies and patterns, calls for an increased overall need for flexibility in the operation and planning of distribution networks. In addition to technological solutions, there is also a clear need for new ways of thinking regarding organising and regulating the DSO business, together with needs for involving the grid consumers / prosumers.

Round Table 1

Integrating Flexibilities: How to Bring Planning and Operation Closer

Technical Committee: Uwe Kaltenborn (Germany), Theodor Connor (Germany)

In the past planning was based on clear capability limits for network components as well as load and generation schemes. The target was the provision of a suitable infrastructure early enough to meet the load demand, reliability targets, cost effectiveness and easy to operate.

Considering the regulatory framework and the requirements from a more dynamic grid operation the boundary conditions for the grid planning will be modified and the functionality of network components defined.

By application of new technologies the actual margin between the grid planning and the physical limits of components can be reduced and utilised as operational flexibility.
In these times we experience:

In this respect the distribution network with fixed infeed, peak load and low load scenarios is converted into an active system with many variable parameters. One possible answer to the challenges is the close cooperation of planning with active input and interaction with operation.

Round Table 2

How Can Flexibility and Customers Evolve in the Market Place?

Technical Committee: Mark McGranaghan (USA)

Continued integration of renewable and distributed resources creates requirements for increased flexibility in the management of the grid.  These flexibility services include both local and bulk system flexibility needs and individual consumers/prosumers may be able to provide much of this flexibility.  Market systems must be able to accommodate the wide range of flexibility resources that can be integrated with the grid.  This panel will explore the evolution of customer participation (individually, through aggregators or as part of smart communities) in flexibility services through local storage, EV integration, smart appliances, etc. and market approaches to accommodate this participation.
