System and method for controlling microgrid

A method of controlling a microgrid, the method comprising:

• receiving a plurality of input signals, wherein the plurality of input signals comprise a plurality of internal input signals received from individual assets from microgrid assets and a plurality of external input signals received from the bulk grid, a bulk grid operating entity, or combinations thereof, wherein at least one of the microgrid assets comprises an electrical generator of a different type than an electrical generator of another one of the microgrid assets;
• and
• providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions and bulk grid conditions,
• wherein providing tieline control signals to adjust active power comprises generating a plurality of prioritized ΔP control signals, wherein at least one of the plurality of prioritized ΔP control signals corresponds to a power limit, a ramp rate, a ramp rate limit, or a frequency.

A system for controlling a microgrid, the system comprising:

• microgrid assets, at least one of the microgrid assets comprising a different type of electrical generator than an electrical generator of another one of the microgrid assets;
• a tieline for coupling the microgrid to a bulk grid;
• and
• a tieline controller coupled to the tieline and configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, and bulk grid conditions, wherein the tieline controller comprises:
• an active power controller configured for generating a plurality of prioritized ΔP control signals, wherein at least one of the plurality of prioritized ΔP control signals corresponds to a power limit, a ramp rate, a ramp rate limit, or a frequency,
• a reactive power regulator configured for generating a plurality of ΔQ control signals, wherein at least one of the plurality of ΔQ control signals corresponds to a reactive power regulation, a voltage regulation, or a power factor regulation, and
• a dispatch reference selection function for using a participation factor of individual ones of the microgrid assets to provide individual adjustment factors for the microgrid assets for use in generating the tieline control signals.
