Intelligent management of distribution grids „Smart Grid“

Agenda

Why does a distribution grid needs intelligent management?

What is the solution?

Is this solution already available?

Summary

Bilfinger Mauell GmbH page 10

Why does a distribution grid needs intelligent management?

Yesterday and today

New supply structure

due to:

Changed feed-in conditions

Wind power

Photovoltaic energy

Nuclear phase-out

Combined heat and power

plants

Biomass energy

New electrical consumers

Electric vehicles

Heat pumps

Electrical energy storage


Problem 1: Voltage band violation

Impermissible voltage increase

due to PV feed-in

V> DIN EN50160

Effects of voltage band violation acc. to DIN EN 50160 ±10

Overvoltage: Damage to end customer equipment

Undervoltage: Malfunction

Problem 2: Equipment overload

Grid extension – how much is needed?


Conventional versus intelligent grid


DER integration requires a combination of grid

extension measures and implementation of

measuring and control technology


Grid monitoring

Smart grid application for Mainova, Frankfurt

Project Description

Realization of two smart grids in the 400V distribution

grid

Intelligent grid protection instead of large investments

in new power lines

Automatic power control of decentralized generation

Automatic voltage regulation

Integrated grid state estimation

Is the solution already available?


Smart grid application for “DSO”, Ireland

Bilfinger Mauell GmbH is interested in:

Local partnerships for the development and

realisation of similar projects, focused on

the exceptions of the irish grid operators

and local regulations.

Potential in Ireland with local Partners?


Realization step by step


Gradually implementing "intelligence"

in the urban grid!

Summary


Increasing amount of DERs requires intelligent grid management

The solution and it’s components are available

Cost-intensive conventional grid extension can be reduced

The solution is working independently

The solution can be integrated in different IT infrastructures

(Grid operation and service centers)
