One of the basic components of future distribution networks are renewable energy resources (RER). The uncertainty in power production of renewable resources such as wind and solar as well as load is another characteristic of such networks. Conventional power flow methods as a basic tool for power system studies may not be suitable for active distribution networks such as microgrids. In this pap...
In this paper three models derived using Machine Learning techniques (Support Vector Machines, Decision Trees and Shadow Clustering) are compared for approximating the reliability of real complex networks, such as for water supply, electric power or gas distribution systems or telephone systems, using different reliability criteria.
The scale of methane emissions from gas distribution systems has serious consequences for energy security, ensuring the security natural transmission and reducing losses in transport. That is why it important to determine such individual elements infrastructure. It been confirmed that have a significant effect on military EU co untries. emission factor (EF) affected by many other causes. best m...
This paper presents an evaluation framework for Techno-Economic-Environmental (TEE) performance of the Integrated Gas and Electricity Distribution Networks (IGEDNs). The proposed is based on a coupled gas electric load flow model, facilitating consideration all parameters affecting operation IGEDNs, such as different mixtures, temperature, pipeline characteristics electricity network topology. ...
Abstract: Since distribution networks have a large share of the losses in power systems, reducing losses in these networks is one of the key issues in reducing the costs of global networks, including issues Which has always been considered. In this thesis, the reconfiguration of the distribution network in the presence of distributed generation sources (DGs) with respect to two types of bus, P ...
One of the most critical and complex issues in long-term planning of distribution networks is the optimal placement of distribution transformers. In this paper, the optimal placement of distribution transformers was investigated based on a complete and multi-objective function. In the proposed method, location, optimal capacity, and the service area are determined by minimizing costs (investmen...
the natural gas consumption in iran has been continuously increasing due to several reasons including low prices of natural gas, development of gas supply networks, people’s salary increase, incorrect consumption culture and the increase of national economy growth. although, the global natural gas consumption has increased by 38% since 2001, the national consumption in iran has increased by 11...
Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
In many practical distribution networks, managers face significant uncertainties in demand, local price of building facilities, transportation cost, and macro and microeconomic parameters. This paper addresses design of distribution networks in a supply chain system which optimizes the performance of distribution networks subject to required service level. This service level, which is consider...
