Abstract

MAIN OBJECTIVE

This project aims at developing a platform and new services that allow implementing control system to increase the energy efficiency, flexibility and

reliability of European electric grids.

SPECIFIC OBJECTIVES

1. Design a platform that allows implementing control system to increase the energy efficiency of electric grids.

2. Design new business models tailored to new stakeholders and market actors as prosumers and aggregators.

3. Improve the QoS of electric grids through the deployment of energy balancing and resilience algorithms.

4. Guarantee the security and privacy requirements of end users.


Concept (background)

Households want to reduce their energy bills without reducing their comfort levels

regarding the energy consumption

There are available technologies to become a prosumer but customers do not have enough

guarantees to invert and manage these systems by themselves

Energy providers only record the energy consumption and there is not a real interaction to improve the

contract conditions and the invoicing is not totally transparent or it is just not regulated

? In brief, there is still a long way to the integration of end-users in the smart-

grid model become a real fact.


Concept (e-balance framework)

What does e-balance propose? Benefits for customers

The customer who wants to improve the economic conditions would contact the local energy provider, who facilitates the

management system like an Internet provider.

The management unit will negotiate on behalf of the customer and this one will be able to interact through a GUI and add

consumption preferences

This system allows managing smart home appliances and negotiating with the local energy provider in order to improve

the energy invoice daily.

In the case the customers had or wanted distributed energy production or storage appliances, the system would optimise the

customer premises through a set of balancing algorithms.

Concept (e-balance framework)

What does e-balance proposed? Benefits for electric grid management

The DSO will obtain new means/tools to contact the customers and request changing the behaviour in order to guarantee the

electric grid reliability.

All this new information allows making the system resilient, it integrates and takes advantage of distributed energy sources, like

renewable energy and electric vehicles.

Facilitate the distributed production technologies breakthrough, reducing transmission losses and releasing the lines' capacity,

what avoids extra investments for maintenance and extensions. %

New actors and business models

The WP2 is assessing the socio-economic analysis, which new actors are identified and potential business models are defined

“Prosumer”

The customer who can produce and store energy. e-balance supports this user by facilitating the management of all the

appliances through a CMU.

“Aggregator”

The aggregator manages a set of prosumers or users through the LVGMU in order to negotiate better prices and to carry

out suggestions/orders from the DSO.

This third party is in charge of the privacy and security of the required information to manage the whole grid (e.g. this

party exists in UK)

Legal issues have been analysed at European and National level in Portugal, the Netherlands and Poland.

In addition, surveys have been carried out in Portugal, the Netherlands and Poland in order to know the customers' expectations regarding e-balance offers.

Finally, a preliminary study has been carried out regarding which business models will be necessary to launch the e-balance platform.

• The survey analysis in this context (1400 people per country) have shown that only the 4% of customers will be willing to worry for the electric energy price fluctuation in order to change their behaviour.

• The distributed energy production improves the energy balancing of electric grids, however, there are many restrictions in some target countries that brake the integration of renewable energy at home level.



Type of the service provider


Demosites

The project will develop the solutions in two real pilots and one in-lab demo

1 BATALHA (PORTUGAL)

This pilot will run under the medium voltage station of "San Jorge" that has two primary substations for the tests. The electric lines has 32 km, supplies 3900 customers with 20.460 kVA of capacity and 77 secondary substations.

1. Assessment and validation of resilience use cases

1. Assessment and validation

of neighbourhood monitoring (at substation and line level)


Demosites

2 BRONSBERGEN PARK (the Netherlands)

This pilot is composed of a micro-grid that supplies a holiday resort with single family houses, which have PV systems installed (315 kWp), smart appliances and a set of batteries for the electric storage with a rated energy of 700 kWh. This is enough to supply the whole park during 4 hours isolating.

Apart from the power system use cases for

neighbourhoods, it will be analysed those at customer

level.


Demosites

3 IN-LAB (IHP – GERMANY)

This pilot is composed of electronic blocks that simulates the low and medium voltage grid, consumers and prosumers. This "virtual" demo will be used as platform for those control mechanisms that can jeopardize for real systems.
