2 Smart grids Four forces that drive the development Demand for competition in the market Demand to decrease carbon emission Need to secure the reliability of electricity Supporting technology and solutions are available November 5, 2014 Slide 2

3 Smart grids Conclusion 1) Union of the Electricity Industry EURELECTRIC 2) Source: Smart Grids and smart energy regulation can help implement climate change objectives. The smart grid is no revolution but rather an evolution or a process (1 In addition to smart devices (IEDs) there will be smart substations, smart primary equipment, smart appliances (2 ABB has been providing components, subsystems and complete smart grid solution backbones for 25 years, thus we are well prepared for the further evolution of the smart grid.

8 Savon Voima Ltd Overview Separate production of district heating Combined production of heat and electricity Production of water power Savon Voima Ltd is a Finnish energy corporation offering a wide range of services to its customers, providing prerequisites for quality of life and success. It is one of Finland s biggest energy service providers with over 196 million annual revenue. November 5, 2014 Slide 8

9 Savon Voima Verkko Ltd Statistics Savon Voima Verkko Ltd Annual revenue 65,9 million Business profit 21,8 million Customer connected to the electricity grid Electricity grid total km Electricity grid per customer 225 m Investments in ,3 million November 5, 2014 Slide 9

10 Savon Voima Verkko Ltd Distribution grid investments Investments in the electrical grid in the next 15 years will be appr. 700 million Investment areas in To ensure grid capacity, reliability, efficiency and sustainable development on a long term Critical line sections To ensure the power supply in urban areas To prevent large problems To diminish risks To guarantee the safety of the grid November 5, 2014 Slide 10

11 Savon Voima Verkko Ltd Motivation for the project A second phase has been reached in the life cycle of Finnish electrical networks. This is due to changes in the Electricity Market Act as well as the effects of the new regulator model which monitors the distribution business in term of operational performance and sustainable investment plans that serve the future needs. Better reliability Smart grid implementation i.e. Grid Automation We are now building future networks for the next 50 years? Right choices have to be made November 5, 2014 Slide 11

12 Savon Voima Verkko Ltd Motivation for the project A radical reformation of the network strategy in A network model for the future SVV path to reach the the set targets Increased cabling Grid automation New telecommunication solutions November 5, 2014 Slide 12

13 Savon Voima Verkko Ltd Target of the project The control of earth-fault currents and reactive power in rural area mixed networks as a part of network automation - Case Lapinlahti - Ahmo In numbers: 60 km MV-underground cable 90 km LV-underground cable 48 transformer kiosk substations Telecommunication using optical fibre 7 units of equipment for decentralized compensation November 5, 2014 Slide 13

14 Savon Voima Verkko Ltd Project expected results Goals To develop 20 kv equipment for managing reactive power and earth-fault current To take new features from the substations deeper into the distribution grid To look for solutions which enable us for changes in the operation environment in the future To standardize solutions for equipment and operation To ensure the feasibility of the developed solutions in field tests November 5, 2014 Slide 14

15 Savon Voima Verkko Ltd Project challenges and solutions for cabled rural networks Management of earth-fault current and reactive power Earth-fault current is the deciding factor in the problem Solution: a combination of centered and decentralized compensation Earth-fault current Compensation unit capacity in substations reaches almost 100% Approximately 50 % of the compensation needs to be decentralized Reactive power In an average load situation 110 kv in the grid connection point Q=0 Adjustable capacity implemented in substations for managing the reactive power Due to coming reactive power balancing outlines in the future November 5, 2014 Slide 15

16 Savon Voima Verkko Ltd Project challenges and solutions for cabled rural networks New features taken deeper into the distribution grid To continue with the traditional zone concept Target: automatic isolation and control actions in fault situations To prepare for changes in the operation environment Concept of smart transformer kiosks Sensor technology Power quality, distribution network situation Normal mode of use, replacement switches, island operation Decentralized production Telecommunications network using optical fibre November 5, 2014 Slide 16
