Abstract:
A renewable energy generator imposes costs on a power grid from rapid fluctuations in output. A device is disclosed that collects data on renewable power production, meteorological and other information, forecasts short timescale renewable power production then mitigates costs incurred by power fluctuations by modulating the power output, while maximizing power production revenue. Mitigation may be effected by an AC/DC inverter, an energy storage system, demand response or a FACTS device. The magnitude and costs for modulating response required from energy storage, FACTS or other power modulation equipment is thereby reduced.

Abstract:
A device is disclosed that uses short term solar energy forecasting to enhance the use of energy storage coupled to an electrical load. By predicting momentary fluctuations in solar energy output, the energy storage is controlled to avoid short term drops in energy production resulting in higher apparent electrical load and potentially higher demand charges. By enhancing the use of the energy storage, less storage is required to mitigate demand charges, thereby reducing capital costs.
