Independently run single microgrids (MGs) encounter difficulties with inadequate self-consumption of local renewable energy and frequent power exchange with the grid. Combining numerous MGs to form a multi-microgrid (MMG) is a viable approach to enhance smart distribution networks' operational and financial performance. However, the correlation and coordination of intermittent power generation within each MG network pose many techno-economic challenges for energy sharing and trading. This review offers a comprehensive analysis of these challenges within the framework of MMG operations. It examines state-of-the-art methodologies for optimizing multi-energy dispatch and scrutinizes contemporary strategies within energy markets that contribute to the resilience of power systems. The discourse extends to the burgeoning role of blockchain technology in revolutionizing decentralized market frameworks and the intricacies of MMG coordination for reliable and cost-effective energy distribution. Overall, this study provides ample inspiration for theoretical and practical research to the new entrants and experts alike to develop new concepts for energy markets, scheduling and novel operating models for future resilient multi-energy networked systems/MMGs.
独立运行的单个微电网（MG）在本地可再生能源自消耗不足以及与电网频繁进行电力交换方面面临困难。将众多微电网组合形成多微电网（MMG）是提高智能配电网运行和财务绩效的一种可行方法。然而，每个微电网网络中间歇性发电的相关性和协调性给能源共享和交易带来了许多技术经济挑战。本综述在多微电网运行框架内对这些挑战进行了全面分析。它研究了用于优化多能源调度的最新方法，并审视了能源市场中有助于电力系统弹性的当代策略。论述还延伸到区块链技术在彻底改变分散市场框架方面的新兴作用以及多微电网协调以实现可靠且经济高效的能源分配的复杂性。总体而言，本研究为新进入者和专家进行理论和实践研究提供了充分的灵感，以开发能源市场的新概念、调度方法以及未来弹性多能源网络系统/多微电网的新型运行模式。
