• Smooth intermittency
• Minimize reverse power flow, keeps voltage within limits
• Store output and release coincidental with local load
• Control ramp rate

Microgrids… “expected to grow the market opportunity by over 3.5 times between 2015 and 2020, to over $829 million annually.”
Total Microgrid Generation Capacity by End-User and Region(Includes existing and planned capacity)
ONCOR Microgrid
• Utilizes distributed generation – two solar photovoltaic arrays– a microturbine– two energy storage units – four generators
• Energy storage is the backbone
A showcase to promote utilities to rate base energy storage batteries for distribution system support and wholesale market services
Distributed Intelligence with OversightDifficult to Manage Centrally
• Emerging conditions – Multi-directional power flow– More uncertainty– Less time to react– Pressure to reduce outages – More inter-connections– More dynamic operations
• Distributed intelligence is key
