1 Quality infrastructure for Renewables-based Mini-grids Dolf Gielen Director IRENA Innovation and Technology Centre 82 nd IEC General Meeting Industrializing Countries Workshop October 24, 2018 Busan, Republic of Korea

2 About IRENA Inter-governmental agency established in 2011 Headquarters in Abu Dhabi, UAE IRENA Innovation and Technology Centre Bonn, Germany Permanent Observer to the United Nations New York 159 Members 24 States in Accession Mandate: Assist countries to accelerate renewable energy deployment

3 Development and welfare for all SDG7 is an enabler for the other UN Sustainable Development Goals Climate policy an important driver energy accounts for two-thirds of GHG emissions We need cleaner, affordable, reliable and abundant sources of energy Source: IRENA (2017) Rethinking Energy

4 Renewable power rapidly becoming competitive Cost reduction in the period Expected cost reduction in the period % Solar PV 23% Onshore Wind All renewable power options will compete with fossil fuels on price by 2020 Wind and PV are abundant and available in most countries Source: IRENA (2018), Renewable Power Generation Costs in 2017, International Renewable Energy Agency

9 Forthcoming IRENA report on QI for Mini-grids in collaboration with IEC and ARE Report: Quality Infrastructure for mini grids 1. Brief on the market status and costs 2. Quality gaps in mini-grids functionalities 3. Costs an benefits of QI deployment 4. Needed QI in the future 5. Strategies to develop QI 6. QI in policy frameworks Report will be presented at International Off-grid Renewable Energy Conference and Exhibition (IOREC) on October 31 st in Singapore. IEC will take part of this event. To be launched at Q Working with IEC experts from microgrid working group of IEC TC 82 and IECRE.

10 Innovation in control systems for mini-grids requires improved communication standards Opportunity for Innovation Cost Reliability Ease Environment More intelligent controls Improved communications and standards Improved metering and monitoring Simplify connecting equipment together STATE OF THE ART TODAY Specialized and expensive controls Non-economic, non-predictive controls Moderate plug-and-play capability High utility interest, but limited to pilot projects Numerous competing standards One to two hours renewable resource prediction with high accuracy FUTURE Low cost modular controls Economic and predictive controls Seamless plug-and-play capability Standard interconnection terms for utilities Common, open-source standards Day-ahead renewable resource prediction with high accuracy Source: IRENA (2016) Innovation Outlook: Renewable Mini-Grids

11 Innovative Low Voltage Direct Current (LVDC) mini-grids LVDC mini-grids Source: IRENA (2016) Innovation Outlook: Renewable Mini-Grids DC reduces up to 10% the energy losses

12 Quality Infrastructure Gaps for LVDC mini-grids Adjustment of AC standards (plugs, sockets, grounding, overvoltage/current, fault detection) Standardisation of DC voltages, installation guidelines and certifications. This will reduce uncertainty and barriers for contractors. Development of new standards and testing specifically targeting safety, protection and power quality to mitigate any negative perception. Cooperation between the various stakeholders to obtain a comprehensive and universally applicable QI

13 Summary of gaps in standards and quality control for future mini-grids QI Needs Incorporate QI and monitoring mechanisms since the planning and design International standards for seamless transition between gridconnected and islanded operation Clear interconnection regulations Harmonization of IoT-related standards (hardware, cloud, security, industry, privacy) preferably at international level (vs today's multiple mostly private/proprietary standards) Harmonized standards & test procedures of EVs and charging equipment Power to X testing Systemic approach for cybersecurity Need for standards and regulations on data collection DC mini-grids: Adjustment AC standards and DC voltages standardization. Prosumers: transaction safety, performance and cost reporting standardisation

14 Using QI in country regulations for mini-grids USA National Electrical Code: new article about DC mini grids. California and Hawaii: new installations require inverters to provide grid support or smart inverter functions. (UL Test Standards) Tanzania Energy and Water Utilities Regulatory Authority: Latest mini grid regulatory framework allows: -Mini-grids at multiple locations can acquire a single license (> 1 MW) or registration for mini-grids using the same technology (<1 MW); - Allow grid-connected mini-grids to operate in islanded mode when power to a previously isolated mini-supply is not available from the main grid; - Clarity and credibility on the compensation calculation for distribution assets when the main grid connects grid.

15 Using QI in country regulations for mini-grids Puerto Rico Regulation on Microgrids. After hurricane Maria in 2017, Puerto Rico looked to implement more resilient energy systems in their communities. The 2018 regulation defines renewable microgrids as those that can generate 75 % of their energy from renewables. It identifies the applicable codes and standards.
