SI2-SSE: Foundations for MATPOWER as an Extensible Tool for Power Systems 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，其规划和运行方面的进步对经济、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元素。MATPOWER目前的形式已经被广泛使用，特别是在研究和教育方面。这个项目的目的是重组MATPOWER的内部结构以及软件开发平台，使其更容易由其用户和开发人员社区进行定制和扩展。此次重组将有助于提高MATPOWER作为设计和分析未来电力系统的成功研究工具的未来影响力。随着电网向更可持续、经济高效和环境友好的系统发展，将MATPOWER定位为在这一创新和变革领域扩大其作为灵活研究和教育工具的角色具有潜在的深远和变革性的影响。MATPOWER解决了电力系统分析中的一些最基本的问题，即潮流(PF)、最优潮流(OPF)和相关问题，这些问题用于确定系统条件、操作员控制行为和物理定律之间的相互作用产生的稳态电压、电流和潮流。这项工作的目的是扩大和扩大MATPOWER作为研究使能工具的范围，以通过两种具体方式解决未来的电力系统问题。第一是开发项目基础设施，以过渡到并维持社区驱动的协作发展范例。第二是围绕一个通用的模块化架构重新设计核心MATOWER软件，该架构将支持更灵活的用户定制并促进用户的重大贡献，同时保留和增强使其在教育中具有吸引力的简单性。具体地说，新架构将大大简化添加任意新设备模型的过程，例如三绕组变压器、电压相关负载、灵活交流输电系统(FACTS)设备和更复杂的高压直流线路模型。它还将促进包括额外的控制，如远程电压调节、开关分路和变压器以及移相器分接变换。最后，它将作为扩展MATPOWER以处理许多低压配电系统所需的三相不平衡网络建模的基础，从而为许多其他当前和新兴研究领域的使用打开大门。

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. MATPOWER is already widely used in its current form, especially for research and education. The purpose of this project is to restructure the internals of MATPOWER as well as software development platform to make it easier to customize and extend by its community of users and developers. This restructuring will serve to increase 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 (PF), optimal power flow (OPF) and related problems used to determine the steady state voltages, currents and power flows arising from the interactions between 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 develop the project infrastructure needed to transition to and sustain a community-driven, collaborative development paradigm. The second is to redesign the core MATOWER software around a general modular architecture that will enable more flexible user customization and facilitate significant user contributions, while retaining and enhancing the simplicity that makes it attractive in education. Specifically, the new architecture will greatly simplify the process of adding arbitrary new device models, such as three-winding transformers, voltage dependent loads, flexible AC transmission system (FACTS) devices and more sophisticated models of HVDC lines. It will also facilitate the inclusion of additional controls, such as remote voltage regulation, switched shunts and transformer and phase shifter tap changing. Finally, it will serve as the basis to expand MATPOWER to handle three-phase, unbalanced network modeling, as required for many low-voltage distribution systems, opening the door for use in many additional current and emerging research areas.
