The invention relates to a comprehensive index design method of an energy hinge. With the goal of covering the lowest comprehensive cost of the economic cost and the environmental and social cost, comprehensive consideration is given to the installation cost, the maintenance and operation cost and operating years of each conversion equipment and energy storage device in the energy hinge, as well as the carbon emission of each conversion equipment, and the environmental pollution value of each pollutant, and under the condition of satisfying the operational equation constraint of the energy hinge itself and the energy supply conversion response strategy, the minimum comprehensive cost of the energy hinge is planned.
