1. A microgrid system comprising a microgrid controller;
wherein the microgrid controller is configured to receive a plurality of input energy sources comprising: a grid source; a battery; and one or more renewable energy sources;
wherein the microgrid controller is configured to direct output power from the grid source, and the one or more renewable energy sources to: the battery for charging the battery;
wherein the microgrid controller is configured to direct power to an EV charging service by a blend of the one or more renewable energy sources, the battery, the grid source; and
wherein the microgrid controller includes a dynamic storage module configured to determine when and from which of the plurality of input energy sources is used to power the EV charging service, using as input: an EV predictor module based on EV charging load patterns, and historical EV arrival patterns to consume energy from a cheapest source possible of the plurality of input energy sources; and
wherein the dynamic storage module also uses as input:
a renewable source of energy predictor module based on one or more of a location-based historical model, local weather prediction, short-term historical production data, historical geographic records, local climatic conditions, seasonal adjustments, and site specific performance history;
a system behavior module based on one or more of a historical effectiveness of storage at a given site for a given system sizing; site load patterns; and EV charging load patterns; and
a cost function module providing values representing a time-based cost of buying electricity and of selling, storage and retrieval for the input energy sources.
