Abstract

The invention discloses a control-strategy-included optimized scheduling and evaluation system and method of an integrated energy system of an industrial park. The method comprises: at a day-ahead scheduling stage, on the basis of prediction of cold, thermal, and electric load curves, an integrated energy system makes a decision of an optimal day-ahead set output by using the operation economy ofthe integrated energy system as an optimized objective according to performances and capacity parameters of all sets; at a real-time scheduling stage, an obtained load prediction result and a calculated optimal scheduling curve are modified properly in advance for certain time by combining current factor changing situations, and a real-time scheduling instruction is generated at a current time ofoperation of the system to realize system optimization, wherein several kinds of control strategies like off-grid and grid-connected control, direct load control, and user temperature control are usedat the real-time scheduling stage; and on the basis of obtaining the optimal scheduling curve, the system is scheduled further to complete evaluation of energy efficiency indexes like economical, environmental protection, and energy saving indexes of the integrated energy system.

Description
