Elements: MATPOWER for Integrated Smart Grid Research and Education

电力系统是现代社会最基本和最关键的基础设施之一，其规划和运营的进步对经济、环境和社会的影响可能是巨大的。MATPOWER是一套用于电力系统仿真、分析和优化的开源科学软件组件。MATPOWER的一个版本被广泛使用，特别是用于研究和教育。持续科学创新网络基础设施（CSSI）要素奖支持将MATPOWER转换为新的灵活的内部建模体系结构所需的研究。新功能将使MATPOWER能够模拟和优化由传输（平衡）和分配（不平衡）系统组成的集成智能电网网络。这些能力将有助于扩大MATPOWER未来影响的范围，作为设计和分析未来电力系统的成功研究工具。随着电网朝着更可持续、更经济、更环保的方向发展，MATPOWER将在这个创新和变革的舞台上扩大其作为灵活的研究和教育工具的作用，在国内和全球都具有深远和变革性影响的潜力。MATPOWER解决了电力系统分析中一些最基本的问题，即功率流，最优功率流以及用于确定稳态电压，电流和功率流的相关问题，这些问题源于系统条件，操作员控制动作和物理定律之间的相互作用。这项工作的目的是扩大和扩展MATPOWER作为研究支持工具的范围，以两种具体方式解决未来的电力系统问题。首先是围绕新的统一MATPOWER元素模型重构MATPOWER内部，极大地扩展了MATPOWER建模的设备和控制范围，并进一步提高了其可定制性。二是实现多相不平衡系统的建模和综合平衡与不平衡模型。这将扩大MATPOWER的范围。随着分散控制和分布式能源（DER）的扩散，如太阳能光伏、插电式混合动力汽车、本地能源存储和各种主动管理需求，它对许多与现代智能电网相关的当前和新兴研究领域的有用性。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The electric power system is one of the most fundamental and critical infrastructures underlying modern society, and the economic, environmental and societal impacts of advances in its planning and operations are potentially enormous. MATPOWER is a set of open-source scientific software elements for electric power system simulation, analysis and optimization. A version of MATPOWER is widely used, especially for research and education. This Cyberinfrastructure for Sustained Scientific Innovation (CSSI) Elements award supports the research needed to transition MATPOWER to a new flexible internal modeling architecture. The new capabilities will enable MATPOWER to simulate and optimize integrated smart grid networks consisting of both transmission (balanced) and distribution (unbalanced) systems. These capabilities will serve to expand the scope of MATPOWER's future impact as a successful research tool for designing and analyzing the power systems of the future. As power grids evolve toward more sustainable, economically efficient and environmentally friendly systems, positioning MATPOWER to expand its role as a flexible research and educational tool in this arena of innovation and change has the potential for far reaching and transformative impact both nationally and globally.MATPOWER addresses some of the most fundamental classes of problems in power systems analysis, namely the power flow, optimal power flow, and related problems used to determine the steady state voltages, currents and power flows arising from the interactions among system conditions, operator control actions and the laws of physics. The aim of this work is to broaden and extend MATPOWER's reach as a research-enabling tool for tackling future power systems problems in two specific ways. The first is to restructure the MATPOWER internals around a new unified MATPOWER element model, vastly expanding the range of devices and controls modeled by MATPOWER and further increasing its customizability. The second is to implement the modeling of multiphase unbalanced systems and integrated balanced and unbalanced models. This will expand the scope of MATPOWER?s usefulness to many current and emerging research areas related to the modern smart grid, with its proliferation of decentralized control and distributed energy resources (DER), such as solar PV, plug-in hybrid electric vehicles, local energy storage, and various kinds of actively managed demand.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
