Smart Grid - a new paradigm for distribution business?
Jean-Luc RoyBusiness Development Director Europe
Agenda
• Why a smart grid revolution now? • What are the main challenges?• What are the majors impacts on
distribution business? • What are the required changes ?
WHY THE SMART GRID REVOLUTION?
Running today's digital society through yesterday's grid is like running the Internet
through an old telephone switchboard’’‘‘Reid Detchon
Electric utilities are facing four main challenges
Increasing demand for energy and electricity
1
2 Moving towards an environmentally-friendlier energy mix (lower carbon emissions, more renewable energy…)
3Volatile energy prices and critical energy losses
4Emerging large regional transmission networks
All these changes are raising the network complexity
Today’s one-way centralized electricity network…

Towards a dynamic and bi-directional flow of energy and data
Smart grid changes will impact distribution business in all its dimensions
• At the strategic level: a clear roadmap is required in order to allocate resources efficiently and to focus management efforts
• At the operational level: taking advantage of the technological innovations will require drastic changes of business processes and organization
• At the IS/IT level: shifting from information scarcity to abundance requires new approaches and policies in IT/IS in order to capture short-term opportunities while not impeding longer-term objectives
• All across the company: A change program is needed to ensure consistency of all action plans and gain people buy-in and acceptance at all levels of the hierarchy

Critical DMS Capabilities (today)• Modeling
– Size– Version control– Incremental changes– Intuitive Graphical modeling– Interactions with other repositories (GIS, AM, CIS, EMS, …)– Management of Incomplete and Inaccurate Models– Fast and flexible On-lining
• Large scale Operation and Telemetry (Millions points)– 1000’s, 10K, 100K RTUs ?– Millions MV Loads– Model LV Customers– Fast growing models
• Network Analysis robustness– Is Critical to Feeder/Substation Reconfiguration (planned or unplanned Outages)– Is Critical where feeders are strongly loaded (high growth rates)
• Work Management effectiveness– Model accurately work and safety processes– Synchronize with Modeling activities
• Deployment Management– Underestimation of Data/Model Management issues– Business Process adaptation– Resistance to Change
New Issues and Requirements for DMS (1)• Distributed Generation
– Bidirectional flows– Unpredictability– Instability– Modeling in MV and in LV (residential)– Various aggregations levels– Portfolio Management, optimisation– Behaviour during Outages– Operation of Microgrids requires multi-islands Loadflow + Freq calculations
at MV level• Demand Response
– Variability of Load Models– Modeling in MV and in LV (residential)– Various aggregation levels– Manage Event/Signals - Interfaces (MDM, Settlement, CSP, …)– Cold Load pickup after Outage– Portfolio Management, optimisation
New Requirements for DMS (2)• Interoperation with AMI
– OMS and Work Management– DG– Signals/Events from DR– Interface with Metering– Customer modeling– load data at LV level– Load model– Voltages monitor, LV phases balance
• HAN devices / Energy Box– Load Forecast– Load Model
• Volt/Var Control:– Control and Optimisation (Intelligent Electronic Devices + MVDC)
• Storage• Plug-in Hybrid Electric Vehicle:
– Load model: might become very complex, driven by factors external to electricity sector (batteries service chain, automakers, local communities)
Summary: exciting time for DMS applications• Load Forecast: Integrate with multiple engines (Wind, Solar, DR, ..)• DG application (MV and LV units/portfolios)• DR application (MV and LV loads/portfolios)• EMS-like applications down to MV levels
– Generation forecast, scheduling, monitoring and balancing (and dispatch ?)– Look ahead load-flow and security analysis– Training Simulator (e.g.: micro-grid operation/restoration)
• Load flow calculations– Simple one way algorithms will be phased out– Extend to LV => another order of magnitude for model size increase– multi-islands Load-flow + Freq calculations at MV level– Very complex, non static Load Models (DR)
• Micro grid operation tools• Reconfiguration (DG and Micro grid options)• Closer coordination with Customer model (complex load groups, portfolios for
DR, connectivity model)• Extended Interfaces:
– AMI Interface (OMS, load model, DG, DR)– MDM Interface (DR)– Business/Enterprise Interface (e.g.: DR Events to Settlement)
• MVDC management (optimization, reconfiguration strategies, …)
