The changes between multiple power loads affect the normal operation and coordinated management of the integrated energy system.Therefore,a short-term prediction method for multiple power loads under comprehensive energy access is proposed.Using Copula theory,analyze the nonlinear characteristics between multiple power loads and influencing factors,and form a multivari-ate time series.Input it into the least squares support vector machine model to complete short-term prediction of multivariate power loads.Using the fruit fly optimization algorithm to optimize the prediction model,obtain the best prediction results,and achieve short-term prediction of multiple power loads.The experimental results show that when the penalty coefficient is 0.4 and the search dis-tance is 5,the optimal short-term prediction of multiple power loads can be achieved,with a mean square error of 0.6%-2.5%.This indicates that the proposed method has good prediction performance and provides support for the operation and management of the comprehensive energy system.
