The document presents insights from a webinar by Dr. Peter Lilienthal on hybrid microgrids that combine wind and solar technologies to reduce the levelized cost of energy (LCOE). It highlights the role of HOMER software in designing microgrids for diverse applications, including energy access, resilience, and backup for unreliable utilities. The analysis of hybrid systems demonstrates significant cost savings and improved reliability through the integration of renewable resources.
Exploring Use Cases with Wind and Solar in Hybrid Microgrids
- 1. Combining Wind and Solar for LCOE Solutions in Hybrid Microgrids Dr. Peter Lilienthal CEO, HOMER Energy Webinar, January 24, 2019
- 2. The Future of Power The HOMER® software is a platform to accelerate the transition to clean distributed power
- 3. 4 Kinds of Microgrids •HOMER Pro for off-grid microgrids 1. Island Utilities Thousands of diesel-powered utility systems 2. Energy Access 1.3 billion people without power •HOMER Grid for grid-connected DG & microgrids 3. Resilience Sandy changed our view of critical infrastructure 4. Backup of unreliable utilities Millions of diesel generators
- 4. Military Bases Developing Country On- Grid Forward Operating Bases Developing Country Off- Grid Fuel Savings Reduced Emissions Renewable Energy & Electric Vehicle Grid Integration EcotourismCampuses Islands Mines Emergency Services Reliability Microgrids & Their Value Propositions Telecomm
- 5. Too Many Choices Hydro Geothermal Smart grids Micro-grids
- 6. What is best? •It depends on: oResources oLoads oEquipment prices oEquipment performance •A confused mind says “No!” •HOMER fits the pieces together
- 7. HOMER as a communication tool Renewable Advocates Diesel Mechanics HOMER Model Power Engineers Financiers HOMER bridges different worlds
- 8. HOMER Energy • 1992 – 2008 at NREL • 2009: HOMER Energy created with exclusive license • >250,000 people have used HOMER • >90,000 opted-in to hear from us on hybrid system design • De facto global standard for microgrid design • 3 main markets o Energy Access o Island and remote utilities o Grid-connected • > 50,000 projects modeled since 2014 Designing Off-Grid/Mini-Grid systems for over 25 years
- 9. Example HOMER Analysis • Ambon Indonesia
- 10. HOMER shows that wind reduces LCOE even at modest windspeeds Also reduces diesel runtime, battery sizing, and capital cost by 50% or more
- 11. Hybrid Systems •Value of Diversity •Reliability •Complementary resources oDaily variations oSeasonal variations oRandom variations
- 12. Seasonal Complementarity Island power system in Crete
- 13. Why wind? •Higher capacity factors •Evening production •Lower LCOE in good wind regimes •Makes high renewable penetrations more achievable
