The main purpose of this paper is to analyze the sensitivity of system parameters to the performance of the Organic Rankine Cycle (ORC) system quantitatively. A thermodynamic model of the ORC system for binary-cycle geothermal power plants has been developed and verified. The system parameters, such as working fluid, superheat temperature, pinch temperature difference in evaporator and condense...

In this paper, a probabilistic neural network (PNN) based classifier is used to judge the static security of the power system. The proposed classifier classifies the security of the power system based on the voltage profile of each bus in reference to changes in the generation and load profile in the system. The probabilistic neural network is used and compared with the radial basis function ne...

Dynamic Power Management (DPM) is a technique to reduce power consumption of electronic system by selectively shutting down idle components. In this article we try to introduce back propagation network and radial basis network into the research of the systemlevel power management policies. We proposed two PM policiesBack propagation Power Management (BPPM) and Radial Basis Function Power Manage...

This paper presents a novel approach for optimal reconfiguration of radial distribution systems. Optimal reconfiguration involves the selection of the best set of branches to be opened, one each from each loop, such that the resulting radial distribution system gets the desired performance. In this paper an algorithm is proposed based on simple heuristic rules and identified an effective switch...

Electrical power distribution systems are critical links between the utility and customer. They are constructed by one of the three types: radial, open loop and network. They are usually arranged to be radial in operation to simplify over-current protection. Utilities are constantly looking for newer technologies that enhance power delivery performance. One of the several important issues is th...

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...

In this paper an effective method for the purpose of state estimation of fundamental and harmonics signals in the radial power distribution network is presented. In Addition, the application development of this method to the network observability and data processing is considered and analyzed. One of the most advantages of this method is capability of bad data detection and process of them and ...

Recently integrating Embedded Generation units (EGs) in the distribution network gain popularity due to their overall positive impacts on the system they serve. Minimizing the system real power losses and improving the voltage profile of the system are just to name a few. However, suboptimal EG penetration and location might increase the system losses. This paper investigates the EG rating by f...

The energy demand all over the world is increasing rapidly day by day. In traditional power systems, plants are located far away from consumer’s premises. This in turn causes a substantial amount of loss both transmission and distribution. general, distribution system has more losses than occurred on side. It employs that there will be significant difference between generated consumers (physica...
