WHAT IS A MICROGRID?
• Limited generation facilities serving many customers
• Line losses in transmission
• Many smaller generating facilities • Energy is used where it is produced
CENTRAL GENERATION DISTRIBUTED GENERATION
EUEC 2015
MICROGRID: • Comprised of distributed generation sources, storage, energy management, and loads • Capable of operating independently
6
SYSTEM DESIGN
: Configuring multiple electrical and mechanical systems together to ensure the energy needs of a building or site are met at all times.
IMPORTANT FACTORS • Projected load • Available space • System cost • Resource availability
• Solar Insolation • Wind speed • Daylight hours • Temperature
CHALLENGES • Match production and load (100%
uptime) • Accurately predict system
performance • Resource fluctuation/Seasonality • Predictability for financing
