Course WT2-01XL: Hybrid Wind/PV/Systems and Micro Grids Fundamentals - extended

with exercises and field trip

The course covers hybrid wind/PV/systems and micro grids, focusing on the technologies, system design, case studies, market development, regional trends and economics. Lectures are supplemented by demonstrations and practical exercises in RENAC’s Training Center in Berlin.

Content

• The course teaches the fundamentals of hybrid renewable-energy systems. The emphasis lies on understanding the various technologies, estimating economic benefits, project planning and the interaction of system components such as small wind plants, PV modules and batteries.
• Practical exercises complement the theoretical material to ensure an optimal learning outcome.
