发电和输电运营和规划之间的密切协调对于具有成本效益和可靠的能源生产和输送至关重要；在所有权多样性存在的情况下，这种协调确实是美国区域输电组织和世界各地类似组织的首要且具有挑战性的目标。单独优化这些部门会忽视潜在的协同效应，而这些协同效应可能有助于更有效地设计和运行电力系统。协调发电和输电决策的协调扩张规划（CEP）与当今的规划和运营尤其相关。造成这种情况的原因有多种，其中包括希望从可再生能源的更深层次渗透中获得最大的环境和经济效益、有效部署新兴存储技术的需要、捕捉和利用运输部门电气化的机会、与其他部门（例如天然气）的相互依赖性增加以及在配电网中容纳分布式能源份额的增加。这些变化导致短期和长期不确定性增加，以及对改进多尺度时空动态表示的需求增加（例如，在多十年扩张模型中表示每小时或每小时一次的跨期耦合）。这项工作的目的是描述 CEP 模型的最新技术，并确定新一代 CEP 模型的电网发展规划和研发 (R&D) 需求的技术挑战。
Close coordination between generation and transmission operations and planning is critical to cost effective and reliable energy production and delivery; such coordination, in the presence of ownership diversity, is indeed a primary and challenging goal of regional transmission organizations in the US and similar organizations worldwide. Optimizing these sectors separately overlooks potential synergies that may allow for more effective design and operation of power systems. Coordinated expansion planning (CEP), where both generation and transmission decisions are coordinated, has become especially relevant to present day planning and operations. There are various reasons for this, some of which include the desire to obtain the most environmental and economic benefit from deeper penetration of renewable energy sources, the need for effective deployment of emerging storage technologies, opportunities to capture and harness the electrification of the transport sector, increased interdependencies with other sectors (e.g., gas), and accommodating increased shares of distributed energy resources in distribution grids. These changes result in increased short-term and long-term uncertainties, as well as an increased need for improved representation of multiscale temporal and spatial dynamics (e.g., representing hourly or sub-hourly intertemporal couplings in multi-decadal expansion models). The purpose of this work is to characterize the state-of-the-art in CEP models and identify technical challenges of grid development planning and research and development (R&D) needs for the new generation of these CEP models.
