Control and Operation of Distributed Energy Storage in Active Distribution Networks

可再生能源技术连同能源效率方面的进步，正在全球范围内用于减少温室气体排放和缓解矿物燃料枯竭所带来的能源危机。可再生分布式发电（RDG）机组，包括光伏（PV）面板和风力涡轮机，将越来越多地连接到配电系统中，这是电力行业智能电网模型中日益增长的一部分。RDG机组是小型、模块化的发电机组，位于用电地点附近。它们被用作传统电网的替代或增强，为公用事业客户提供高质量、可靠的电力。RDG技术也可能有利于推迟电力基础设施的升级。然而，由于安全、经济以及缺乏支持RDG大规模集成的知识和工具，现有电力系统对RDG互连施加了许多限制。为了减小RDG的可变性、不确定性和分布性等特征与有限的电网运行和公用事业监管标准之间的差距，需要进行重要的研究。该计划将研究和开发分布式储能（DES）的最佳控制和运行技术，以确保RDG与电力系统的兼容性。重点将是使用DES来缓解配电系统中由光伏互连引起的电压调节和电力调度问题。该项目的成果将为已解决的RDG并网问题提供解决方案，使RDG的利用效率最大化，使RDG更好地并入电网，从而激励越来越多的RDG被公用事业公司和客户使用。该项目还将为加拿大公用事业公司带来最新的知识和工具，为RDG技术的广泛应用做好准备。此外，通过该项目培养的高素质人才将获得加拿大工业界和学术界所需的知识和技能，以加速加拿大智能电网的实现。

Renewable energy technologies, together with advances in energy efficiency, are being used globally to reduce greenhouse gas emissions and to relieve the energy crisis brought on by the depletion of fossil fuels. Representing a growing part of the smart grid model for the electric power industry, renewable distributed generation (RDG) units including photovoltaic (PV) panels and wind turbines will be connected to the power distribution systems in increasing numbers. RDG units are small, modular, electrical energy generation units located close to where electricity is used. They are used as an alternative to or an enhancement of the traditional electric power grid to provide high-quality, reliable electricity at the utility customer sites. RDG technologies may also be beneficial in delaying electric utility infrastructure upgrades. Existing power systems, however, impose a number of constraints on RDG interconnection because of safety, economics, and lack of knowledge and tools to support large-scale integration of RDG. Significant research is needed to mitigate the gap between the characteristics of RDG such as variability, uncertainty and distribution, and the restricted grid operation and regulation standards of utilities. The proposed program will investigate and develop optimal control and operation technologies for distributed energy storage (DES) to ensure compatibility of RDG with the power systems. The focus will be on employing DES to mitigate the voltage regulation and power dispatch issues caused by PV interconnections in distribution power systems. The outcomes of this program will provide solutions for the addressed RDG interconnection problems so that the utilization efficiency of RDG can be maximized and RDG can be better integrated into the grid, which will incent more and more RDG to be used by utilities and customers. The program will also bring up-to-date knowledge and tools to Canadian utility companies and prepare them well to meet the widespread applications of RDG technologies. In addition, the trained highly qualified personnel through the program will gain the knowledge and skills needed by Canadian industry and academia to accelerate the smart grid realization in Canada.
