Networks with conventional Generation & Loads. History?

Unidirectional flows from transmission to end consumerPredictable, low DG penetration if anyLow monitoring and control on MV/LV if any (“passive control”)Centralized control on conventional generation and transmission“Fit and forget” approach – most issues solved in network planning stage

* DG – Distributed Generation


Networks of Today and Tomorrow?

New challenges = New task for Energy Market Roles?

5

Grid challenges set new requirements for the market roles and interaction

“Asset value”

“Energy value”

Revenue assurance, Outage prevention and reduction of downtime

Dynamic capacity management - Peak shaving instead of peak generation

Balancing power, Energy efficiency and optimization

Supply response and portfolio optimization

Integration of renewable energy resources: wind, biogas, photovoltaic

Infrastructure/asset protection and optimization


Example: Quality of electric power supply

6

Continuity of power supply in grids – SAIDI, SAIFI, ENS, AIT...Planned vs non-planned (fault) outagesFault location and restoration timeWeather conditionsRatio of overhead lines and cable

Ability of power distributor or producer to respond to applicable requirements of end customers (commercial quality)

Not directly related to the physical operation of systems

Incentive/penalty mechanismsMotivational quality controlSAIDI, SAIFI, ENS… as reliability parameterPenalties as percentage of annual network fee, average value of ENS, …

SAIDI - System Average Interruption Duration Index SAIFI - System Average Interruption Frequency IndexENS - Energy not supply AIT - Average Interruption Time

Interaction of Smart Grid and Smart MarketEnergy Price vs. Network Capacity – Congestion Management

21

Smart Market operates with fictive price as “control signal”strives for power balance (demand/supply)

Smart Grid uses “physical measurements” for controlsstrives for grid usage optimization

Congestion management has priority, results in grid measures first and end-consumer measures last; it must be transparent, objective & non-discriminatory!
