چکیده مقاله :
با توسعه منابع انرژی هیبریدی و ذخیره‌سازهای انرژی الکتریکی، بهره‌برداری از شبکه‌های توزیع انعطاف‌پذیری بیشتری پیدا کرده است. به‌منظور کاهش هزینه‌های بهره‌برداری، مدیریت بهینه این منابع در شبکه توزیع ضروری است. از آنجا که مالکیت این منابع معمولاً خصوصی می باشند، لازم است در تابع هدف، علاوه بر هزینه بهره‌برداری، درآمد مالکان نیز لحاظ شود. این تحقیق یک مدل بهینهسازی برای مکان‌یابی و ظرفیت‌یابی منابع انرژی هیبریدی در کنار نیروگاه تلمبه ذخیره‌ای ارائه می‌دهد تا ریزشبکه‌ای با قابلیت بهره‌برداری به صورت جزیره‌ای طراحی شود. مدل پیشنهادی از دیدگاه بهره‌برداری شبکه توسط تجمیعکننده منابع انرژی ارائه شده است. تابع هدف شامل کاهش هزینه تلفات، هزینه تأمین انرژی، افزایش منافع تجمیعکننده و بهبود قابلیت اطمینان شبکه می باشد. عدم قطعیت‌های توان مصرفی و تولیدی منابع در قالب سناریوهای زمانی مدل‌سازی شده و از الگوریتم بهینهسازی مبتنی بر یادگیری و آموزش در نرم‌افزار متلب برای بهینه سازی استفاده شده است. نتایج شبیه‌سازی روی شبکه توزیع 69 باس استاندارد، نشان‌دهنده برتری مدل پیشنهادی در کاهش هزینه‌ها و افزایش درامد تجمیعکننده منابع می باشد.
With the development of hybrid energy resources and electrical energy storage devices, the operation of distribution networks has become more flexible. In order to reduce operating costs, optimal management of these resources in the distribution network is essential. Since the ownership of these resources is usually private, it is necessary to include the owners' income in the objective function, in addition to the operating cost. This research presents an optimization model for locating and capacity finding hybrid energy resources next to a pumped storage power plant to design a micro-grid with the ability to operate as an island. The proposed model is presented from the perspective of network operation by the energy resource aggregator. The objective function includes reducing the cost of losses, the cost of energy supply, increasing the benefits of the aggregator, and improving the reliability of the network. The uncertainties of the consumed and produced power of the resources are modeled in the form of time scenarios, and the teaching learning based optimization algorithm in MATLAB software is used for optimization. Simulation results on a standard 69-bus distribution network indicate the superiority of the proposed model in reducing costs and increasing resource aggregator revenue.
