The present disclosure presents a system, method, and apparatus for capacity determination in a micro grid, and a tangible computer readable medium. The micro grid comprises multi-type energy supply devices to provide both electricity and thermal energy, In embodiments of the present disclosure, a capacity determination process for minimizing both annual integrated cost for the micro grid and annual energy outage cost, is performed under constraints on electricity supply/demand balance and thermal energy supply/demand balance, and operation constraints on the multi-type energy supply devices, to determine respective numbers or energy supply capacity of the multi-type energy supply device. With embodiments of the present disclosure, it may achieve an optimal capacity termination which could provide a significant cost saving and at the same time guarantees the operation reliability of the micro grid.

System, method and apparatus for capacity determination for micro grid and tangible computer readable medium

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.
