A method for scheduling a commercial district building micro-grid considering central air conditioning demand response

Abstract

The application provides a kind of business circle building micro-grid scheduling method considering central air conditioning demand response, steps include: obtaining the equipment operating parameters of central air conditioner, calculating the nonlinear characteristics of energy efficiency ratio with partial load rate and determining physical constraints, establishing a refined multi-cool machine central air conditioning system physical model;Obtain building thermal parameters, indoor and outdoor real-time temperature and thermal comfort temperature interval, quantify the adjustment margin;Integrate micro-grid other equipment operating parameters, central air conditioning physical model and adjustment margin, establish micro-grid basic optimization model, for the three-stage optimization micro-grid basic optimization model constraint conditions and objective function of pre-regulation, demand response regulation and post-regulation, strengthen the cold balance constraint as a distributed robust opportunity constraint, then linearization treatment, finally obtain mixed integer programming model and solve to obtain the optimal day-ahead scheduling scheme.The application significantly reduces the system operation cost on the basis of ensuring building thermal comfort and reliable cooling.
