Abstract: With the increasing penetration of renewable energy resources (RES), different types of electricity market entities, such as traditional thermal power, energy storage, and RES, have demonstrated distinct differentiated characteristics in terms of the core attributes of supporting the operation of power systems and society. To address the issue that the current electricity market mechanism struggles to comprehensively and accurately quantify the contributions of different market entities in dimensions such as safety and environmental friendliness, this paper proposes a multi-value evaluation method for power systems oriented towards multiple types of entities. Firstly, an evaluation index system and calculation model covering economic value, security value, and environmental value are established. The Vickrey-Clarke-Groves (VCG) auction mechanism is introduced, and based on the joint optimization clearing model of main and auxiliary services in power systems, the multiple values of various market entities are quantified through alternative benefits. Secondly, to tackle the problems of heavy computational burden in the VCG framework and high solving complexity of the security-constrained unit commitment (SCUC), a parallel solving acceleration algorithm based on time-period decoupling and state-space compression is proposed. Case studies are conducted on the modified IEEE 30-bus and IEEE 118-bus systems. The results demonstrate that the proposed method comprehensively and objectively evaluates the multiple values and externalities of various market entities, and the proposed acceleration algorithm significantly improves the solving efficiency of mixed-integer linear programming (MILP) problems while meeting the requirements of solving accuracy.
