1 From NTNU to three villages in South America, Africa and Asia
UiO Energy seminar: The rural energy challenge Oslo, March 11th, 2015 Converting Knowledge into Action: From NTNU to three villages in South America, Africa and Asia Marta Molinas Jon Are Suul Professor pos.doc. Department of Engineering Cybernetics Department of Electric Power Engineering Norwegian University of Science and Technology Trondheim, Norway

2 From NTNU to the World NTNUs Vision: "Knowledge for a better world"
Trondheim Earth Institute Columbia Univ. Bhutan Tanzania Paraguay NTNUs Vision: "Knowledge for a better world"

3 Motivation "Knowledge for a better world" Electricity access to all:
Much knowledge is available at Universities that already "today" can provide solutions to urgent real problems in the developing world To do something that can reach the poorest and most vulnerable people on the planet Electricity access to all: Focus on regions areas where reliable electric power supply is unavailable or where electricity access is scarse Increase local awareness of and practical utilization of freely available renewable energy sources Applications where better access to electric power can significantly improve the daily living conditions of people

4 Background Engineers Without Borders at NTNU (->2011)
RenPEACE (2010) – "Professors Without Borders" "Master med Mening" – NTNU First projects supervised by Prof. Molinas in Two students analysing a rural MicroGrid in Wawashang, Nicaragua Resource assessment of micro-hydro potential and sizing of PV generation cluster for integration in existing MicroGrid Sabbatical year of Prof. Molinas Fellowship from the "Gross National Happiness Commission" of Bhutan 3 months stay in Thimpu, 2 months in Phuentsholing Sabbatical stay at the Earth Institute, University of Columbia, New York

5 Engineers without borders
Master Thesis Concept Prof. without borders Engineers without borders Master Thesis New Master Thesis Concept

6 Professors without borders - 2012

7 "Master med Mening"

8 Example cases C1: Desalination plant with solar PV in Paraguay C2: Solar PV Microgrid in Bhutan Royal University of Bhutan, College of Science and Technology C3: Microgrid in secondary school in Tanzania

9 C1: Desalination plant with solar PV in Paraguay
2 Master Projects at NTNU, Ingerid Zeiner: “System Design and Analysis of Electricity Provision for a Desalination Plant – A study for Pozo Colorado, Paraguay” Preliminary design of reverse osmosis desalination plant to cover fresh water demand in Pozo Colorado System design and sizing of grid-connected power supply with PV back-up for improved reliability System design of stand-alone PV MicroGrid for desalination Johannes Waatevik: "Design of a Microgrid for a Desalination Plant in Pozo Colorado, Paraguay" Study of electrical system configuration and control of power converters in the system

10 Study case Pozo Colorado
Located in the Gran Chaco area of Paraguay Dry, underdeveloped region of the country Population: about 1700 inhabitants Expected water demand: 270 m3/day Insufficient power supply with existing 22 kV power system Increased reliability with new line in 2014 1 min (3 acc) The price in cents is in cents of what currency???? – US Dollars

11 Study case Pozo Colorado
Current situation: Surface water used as source of drinking water Not a clean water source: chemical processing needed Not reliable in dry periods Previously designed water supply system based on centralized chemical treatment was not functional Ground water is available but has high salinity Desalination is necessary for safe and reliable water supply 1 min (4 acc)

12 Desalination System Overview
Based on Reverse Osmosis Well pumps, pre-treatment pumps, high pressure pumps and distribution pump for operating the plant Dependent on reliable power supply

13 Outcomes from activities until now
Academic results at NTNU 2 completed Master Projects 2 conference publications: Ingerid Zeiner, Jon Are Suul, Marta Molinas, "Competitiveness of Grid Connected Photovoltaic Power Supply for a Desalination Plant under a Prospective Power Market in Paraguay," in Proceedings of The 2nd IEEE Conference on Power Engineering and Renewable Energy, ICPERE 2014, Kuta, Bali, Indonesia, 9-11 December 2014, 6 pp. Ingerid Zeiner, Jon Are Suul, Aldo Marcos, Marta Molinas, "System Design and Load Profile Shaping for a Reverse Osmosis Desalination Plant Powered by a Stand-Alone PV System in Pozo Colorado Paraguay," in Proceedings of the 2014 Ninth International Conference on Ecological Vehicles and Renewable Energies, EVER 2014, Monte-Carlo, Monaco, March 2014, 7 pp. Local application for governmental funding to develop the designed desalination plant Application for establishment of a MSc program on electric power conversion and renewable energy at the National University of Asuncion in cooperation with NTNU 1 min (5 acc)

14 C2: Solar PV Microgrid in Bhutan
Project in cooperation with Royal University of Bhutan (RUB), College of Science and Technology (CST), Phuentsholing Development of a Solar PV Microgrid as a demonstration facility for educational purposes at the College Campus Master Projects at NTNU, Håkon Duus: Development of methodology for planning and energy system analysis of MicroGrids based on the investigated case

15 Current situation in Bhutan
Political target to quickly achieve 100 % electricity access Slower expansion of the national grid Important to ensure grid compatibility of developed MicroGrids Source: Bhutan Living Standards Survey 2012 Report

16 Planned Microgrid Demonstration
Funding granted by UNDP Project in cooperation with RUB, NTNU and Earth Institute

17 Earth Institute – Modi Research Lab
Shared Solar: Prepaid Electricity via Mobile Telephony Sharedsolar weblink:

18 Plan for building long-term cooperation
International Master Programme Gateway to Columbia University Prototype Microgrid Virtual Mobility Lectures International Linkage Policy screening excercise using the GNHC Policy lens…. Expected Outcome: self-standing academic relations between RUB, NTNU and Modi Research Lab at Earth Institute based on the 6 year inception period of the International Master Programme

19 Expected Outcomes Academic results at NTNU
New MSc Projects Technical advances and scientific publications H. Duus, S. Mandelli, M. Molinas, O.Fosso, “A methodology for supporting the planning of micro-grids based on composable tools: A case in Bhutan,» in IEEE International Youth Conference on Energy, Pisa 2015 Capacity Building: Improved facilities for training and education at RUB CST In 2016: A joint 6-year MSc program between NTNU and RUB on Hydro power and MicroGrids (application to NORAD) Initial phase: Main study at NTNU, 3-4 months at RUB Final phase: Master Program at RUB, 3-4 months stay at NTNU Self sustainability of Master Program at CST by 2022 1 min (5 acc)

20 C3: Microgrid in Tanzania
Project in cooperation with Politecnico di Milano and local communities in Tanzania Restoration and expansion of a Microgrid for the secondary school in the Ngarenanyuki village in Northern Tanzania Part of the initiative "Energy4Growing" Exchange stay of PhD candidate Stefano Mandelli at NTNU in 2014 DIPARTIMENTO DI ENERGIA

21 Existing system in Ngarenyuki
Run-off-the river Micro-hydro No governor Dump-load for frequency control Small battery storage Petrol generator as back-up power supply Manual switching between sources Frequent blackouts

22 Upgraded MicroGrid System

23 Upgraded MicroGrid system
AC system Double bus-bars Micro-hydro generator Dump-load Diesel Generator Local loads Programmable Logic Controllers (PLCs) and monitoring system DC system PV panels with MMPT Lead acid batteries Bidirectional converter capable of grid forming & grid following operation Should be prepared for grid connected operation Political decisions to expand the national HV distribution grid to the Uncertain time frame
