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.

可再生能源技术以及能源效率的进步正在全球范围内被用来减少温室气体排放并缓解化石燃料枯竭带来的能源危机。作为电力行业智能电网模式的一个重要组成部分，包括光伏（PV）面板和风力涡轮机在内的可再生分布式发电（RDG）单元将越来越多地连接到配电系统。RDG装置是小型的模块化电能产生装置，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技术也可能有利于延迟电力公用事业基础设施升级。 然而，现有的电力系统，施加了一些限制RDG互联，因为安全性，经济性，以及缺乏知识和工具，以支持大规模集成的RDG。需要进行大量的研究来缩小RDG的特性（如可变性、不确定性和分布性）与受限制的电网运行和公用事业监管标准之间的差距。拟议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。重点将是采用DES，以减轻电压调节和配电系统中的光伏互联所造成的电力调度问题。 该项目的成果将为RDG互联问题提供解决方案，从而最大限度地提高RDG的利用效率，更好地将RDG纳入电网，这将激励越来越多的RDG被公用事业和客户使用。该计划还将为加拿大公用事业公司带来最新的知识和工具，并为他们做好准备，以满足RDG技术的广泛应用。此外，通过该计划培训的高素质人员将获得加拿大工业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。
