The invention discloses a Min-Min heterogeneous network scheduling electric power system resource allocation method based on an improvement. When a group of electric power service requests are obtained, and corresponding resources are obtained after an application, firstly, an average value and a minimum value of operation time of each task on a power grid processor are calculated; secondly, the minimum value is subtracted from the average value; thirdly, the minimum execution time of a long task in an isomorphism disequilibrium system is subtracted from the average execution time to obtain a value which tends to be greater than a corresponding value of a short task, and therefore a higher priority of an existing long task request is guaranteed, and load balancing is realized; and lastly, Min-Min heterogeneous network scheduling electric power system resource allocation based on the improvement is finished. Through the Min-Min heterogeneous network scheduling electric power system resource allocation method based on the improvement, an inspired strategy is used for improving a resource scheduling strategy in an electric power system cluster so that the effects that computer loads are balanced and the resources are effectively scheduled can be achieved, and usability of the system is improved.
