  • 2. © Siemens AG 2014 All rights reserved. Page 3 2013-09-25 Klaus Arzig Definition Wikipedia: A smart grid is a modernized electrical grid that uses analogue or digital information and communication technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity Roll-out of smart grid technology also implies a fundamental re-engineering of the electricity services industry, although typical usage of the term is focused on the technical infrastructure BDEW: Adds also gas (H2, Methane,…) to it, which might end up in an overall view of an energy network including heating, cooling, energy storage etc.

Page 17 2013-09-25 Klaus Arzig Demand Response General Definitions of Demand Response FERC Federal Energy Regulation Commission “Changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.” http://www.ferc.gov/industries/electric/indus-act/demand-response/dr-potential.asp Paolo Bertoldi, European Commission, DG JRC, IE- Institute for Energy: “Demand response is a series of programs sponsored by the power grid, the most common of which pays companies (commercial DR) or end-users (residential) to be on call to reduce electricity usage when the grid is stressed to capacity. […] DR is different from reduction in load and energy consumption due to real time, time of use, or peak time tariffs, where end-users decide to act on its own consumption to reduce costs.” http://iet.jrc.ec.europa.eu/energyefficiency/workshop/international-workshop-potential-and-programmes-foster-demand-response-europe Load follows generation to avoid high electricity prices or maintain reliable electric services.

Page 22 2013-09-25 Klaus Arzig Non-technical losses Trends Integration of renewables Technologies and standards Customer challenges Integration of renewables: Share of renewables to increase dramatically in the next 2 decades, bringing urgent need for grid integration, e.g. in EU, share of renewables expected to rise to 38% in 2030 Smart meters add more measurements into the grid to enhance the control Non-technical losses: E.g. in Brazil (5.8%) due to non-technical causes, e.g. electricity theft Market regulation: Regulation in key markets drives adoption; Europe, USA and China have regulations in place. Smart meter as a key component in demand response scenarios Regulations Smart metering solutions support changes in distribution grids
