7 “The Smart Grid will be a customer-centered, interactive, reliable, flexible, optimal, economical, economically responsive and, ultimately, a sustainable and environmentally responsible electrical power generation and distribution system. Electric utilities must play a key role in its development.” Smart Grid Technology Innovation Group Report, Tokyo Summit 2010 Why Smart Grids are requested

8 Towards intelligent networks

9 Improving Power Quality Increase efficiency of power systems Reducing pollution Reducing system losses Supporting large-scale penetration of small-scale DGS Reducing primary energy consumption Creation of green jobs Implementing Smart Grids Advantages

10 Network devices potentially critical Feeder circuit breakers Protection devices Conductors On Load Tap Changer (OLTC) Critical issues in the electrical network management system Voltage regulation Harmonic pollution Grid disconnection Islanding Implementing Smart Grids Critical items

11 Optimal voltage regulation is one of the main issues to address in a Smart Grid context Voltage regulation

12 12 Traditional Voltage Regulation On Load Tap Changing Transformer Traditional Voltage Regulator Strategies applied in MV distribution systems could be not able to manage high penetration of DG plants  Not able to manage active feeder  Fail when the HV/MV power flow partially or completely reverses

13 13 Energy Storage System  Renewable sources integration  Peak load leveling  Power quality improvement  Islanding operation One possible solution

14 14 Energy Storage System What kind of storage  Pumping Hydro  Electrochemical  Compressed air  Super-capacitor  SMES  Fuel cell Short-Term Response Energy Storage (Seconds) Long-Term Response Energy Storage (Hours) Real Long-Term Response Energy Storage (Days) Seconds Hours Days MWh [MW] [Time]

15 15 Simulation A power flow problem  1 HV/MV Transformer (25MVA)  12 MV buses (2 dedicated to DGs)  366 nodes  PVGIS model  Annual load curve  PV nominal power installed 23MW  MatPower environment

16 16 Simulation results January PV production Power flow Power absorption Power (MW) Time (h)

17 17 Simulation results February PV production Power flow Power absorption Power (MW) Time (h)

20 20 Islanding “A condition in which a portion of the utility system that contains both loads and distributed resources remains energized while isolated from the remainder of the utility system”. (IEEE Std. 100-2000 )

21 21 Why islanding occurs IEEE Std. 929-2000 In this case normal protections does not stop the DG to energized the Point of Common Coupling (PCC ) Line disconnection + Power balance between source and load High probability that Islanding occurs

22 22  Safety issues for the line workers  Distributed inverters and generally customers devices could be damaged  Responsibility of DSO towards customers Islanding Critical items

23 23 How Islanding occurs Feeder circuit breaker: off Feeder circuit breaker: on MV/LV substation micro-grids
