Microgrid: • Interconnected loads and

distributed energy resources with defined electrical boundaries

• A single controllable entity that can connect and disconnect from the grid

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
