A Review of Electric Vehicle V2G Coordinated Dispatch Strategies for Distribution Grid Flexibility

Abstract

This study focuses on V2G-based coordinated scheduling strategies for enhancing the flexibility of distribution networks using electric vehicles (EVs). Through a systematic review of relevant literature from databases such as IEEE Xplore and CNKI, we analyze existing research on technical approaches such as algorithm optimization, real-time control, and system-level coordination such as equipment integration and multi-agent collaboration. Key challenges are identified, including the lack of standardized cross-brand protocols, conflicts of interest among multiple stakeholders, and stability risks under high EV penetration. We propose future research directions, such as developing dynamic matching mechanisms, designing universal benefit-sharing schemes and building robust scheduling models. This work provides theoretical insights for in-depth studies on EV-grid synergy.
