it is expected that, compared with other power plants, changes in fuel cost for power plants in the deregulated electricity market leads to changes in the generation capacity of wind power plants. to quantify this effect, this article aims at modeling energy generation capacity and supply or distribution of different power plants as opposed to those of wind power plants. the proposed model was ...

برای هماهنگی آسان تر رله های جریان زیاد در شبکه های بزرگ و بهم پیوسته لازم است تا رله هایی به عنوان نقاط شروع هماهنگی یا همان نقاط شکست تعیین شود، نقاطی که در آن حلقه های شبکه در دو جهت ساعتگرد و پادساعتگرد باز می شوند. در گذشته روشی مبتنی بر سیستم خبره، عواملی همچون محل منابع و یا سطوح اتصال را درقالب قوانین خبره درنظرگرفته و باتوجه به آن ها به تعیین نقاط شکست پرداخته است. اما تعیین کوچکترین م...

Environment and the need to protect and care for it, is one of the main concerns of industrial development in todaychr('39')s society; and air pollution is one of the most noticeable and tangible causes of it. The increasingly growth of the industry has led to the production and diffusion of gaseous pollutants into the air and among them; thermal power plants are one of the most important sourc...

the long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. this article considers the problem of economic development in macro level. as economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...

This paper presents an online two-stage Q-learning based multi-agent (MA) controller for load frequency control (LFC) in an interconnected multi-area multi-source power system integrated with distributed energy resources (DERs). The proposed control strategy consists of two stages. The first stage is employed a PID controller which its parameters are designed using sine cosine optimization (SCO...

Prony Analysis is a technique used to decompose a signal into a series consisting of weighted complex exponentials and promises to be an effi cient way of recognizing sensitive lines during faults in power systems such as the U.S. Power grid. Positive Sequence Load Flow (PSLF) was used to simulate the performance of a simple two-area-four-generator system and the reaction of the system during a...

Business intelligence (BI) is a key topic in business today, since it is focused on strategic decision making and on the search of value from business activities through empowering a “forward-thinking” view of the world. From this perspective, one of the most valuable concepts within BI is the “knowledge discovery in databases” or “data mining,” defined as “the process of discovering meaningful...
