US 10,122,166 B2 · System for integrated multi-energy scheduling control in a micro-grid

Abstract

A system provides integrated multi-energy scheduling control in a micro-grid. The micro-grid may comprise a combined cooling, heating and power CCHP unit and an ice-storage air conditioner. In embodiments, an integrated multi-energy scheduling control process for operation in the micro-grid is performed, based on the predicted electricity demand and cooling demand and the predicted renewable energy output, under process constraints to determine the amount of electricity exchanged between the micro-grid and a macro-grid, cooling power output and electricity output of the CCHP unit, and operation modes and cooling power output of the ice-storage air conditioner in time intervals in a scheduling period, wherein electricity supply/demand balance and cooling energy supply/demand balance are coupled. The system may achieve multi-energy supply/demand balance at a minimized operational cost, and may achieve a high energy efficiency of both the CCHP units and a high performance of the ice-storage air conditioner.
