This paper first conducts a comparative study of the management system of private colleges and universities at home and abroad, then analyzes the reference significance of the management system of foreign private colleges and universities for the development of private colleges and universities in China, and finally puts forward corresponding strategies for the construction of a management system for private colleges and universities, so as to effectively promote the rapid development of private colleges and universities in China. At the same time, a smooth-running of private higher education is directly related to national development and the future of the nation. Private colleges and universities shoulder the sacred mission of educating people for the party and the country. Carrying out the party’s national work in the new era is the internal requirement of comprehensively implementing the party’s educational policy, the fundamental task of building morality and cultivating people, the mission of the era of developing schools and strengthening the country, as well as achieving satisfactory education. This helps to improve the socialist education system in China.

A microgrid energy management system (MEMS) optimally schedules the operation of dispatchable distributed energy resources to minimize the operation costs of microgrids (MGs) via an economic dispatch (ED). Actual ED implementation in the MEMS relies on an optimization software package called an optimization solver. This paper presents a comparative study of optimization solvers to investigate their suitability for ED implementation in the MEMS. Four optimization solvers, including commercial as well as open-source-based ones, were compared in terms of their computational capability and optimization results for ED. Two-stage scheduling was applied for the ED strategy, whereby a mixed-integer programming problem was solved to yield the optimal operation schedule of battery-based energy storage systems. In the first stage, the optimal schedule is identified one day before the operating day; in the second stage, the optimal schedule is updated every 5 min during actual operation to compensate for operational uncertainties. A modularized programming strategy was also introduced to allow for a comparison between the optimization solvers and efficient writing of codes. Comparative simulation case studies were conducted on three test-bed MGs to evaluate the optimization results and computation times of the compared optimization solvers.
