Accountability in Smart Microgrids Based on Conservative Power Theory
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-01)
Smart microgrids offer a new challenging domain for power theories and metering techniques because they include a variety of intermittent power sources which positively impact on power flow and distribution losses but may ...
Friction losses in valves and fittings for power-law fluids
(Brazilian Society of Chemical Engineering, 2003-10-01)
Data on pressure drop were obtained in stainless steel, sanitary fittings and valves during laminar and turbulent flow of aqueous solutions of sucrose and xanthan gum, which were selected as model fluids. The rheological ...
Artificial immune networks Copt-aiNet and Opt-aiNet applied to the reconfiguration problem of radial electrical distribution systems
(Elsevier B.V., 2015-02-01)
This paper presents two new approaches to solving the reconfiguration problem of electrical distribution systems (EDS) using the Copt-aiNet (Artificial Immune Network for Combinatorial Optimization) and Opt-aiNet (Artificial ...
A new method for real time computation of power quality indices based on instantaneous space phasors
(Elsevier B.V., 2007-01-01)
One of the important issues about using renewable energy is the integration of dispersed generation in the distribution networks. Previous experience has shown that the integration of dispersed generation can improve voltage ...
Use of a multi-objective teaching-learning algorithm for reduction of power losses in a power test system
(Universidad Nacional de Colombia Sede Medellín, 2014-06-25)
This paper presents a multi-objective teaching learning algorithm based on decomposition for solving the optimal reactive power dispatch problem (ORPD). The effectiveness and performance of the proposed algorithm are ...
Mathematical optimization versus Metaheuristic techniques: A performance comparison for reconfiguration of distribution systems
(2021-07-01)
Reconfiguration is a complex combinatorial problem in which the topology of distribution systems is modified by the opening/closing of interconnection switches aiming techno-economic benefits (e.g., minimization of losses). ...
Power Flow Maximization in Permanent-Magnet Generators
(Institute of Electrical and Electronics Engineers, 2014-02)
The main hypothesis proposed in this paper is that by controlling the harmonic and zero-sequence components of the current in nonsinusoidal permanent-magnet synchronous generators (PMGs), additional energy can be obtained, ...
INSTALLATION OF WIND POWER AND ESTIMATIVE OF ENVIRONMENTAL LOSSES IN A SECTOR OF THE WEST COAST OF CEARA, BRAZIL
(Univ Federal Ceara, Programa Pos-graduacao & Filosofia, 2015-10-01)
Brazil, which relies on hydroelectric power, has developed other sources of renewable energy, mainly wind power. The state of Cear, in the northeastern region, has a potential wind power of 26.2 GW; however, this form of ...
A New Approach for Nontechnical Losses Detection Based on Optimum-Path Forest
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02-01)
Nowadays, fraud detection is important to avoid nontechnical energy losses. Various electric companies around the world have been faced with such losses, mainly from industrial and commercial consumers. This problem has ...
Enhancement of simultaneous network reconfiguration and DG sizing via Hamming dataset approach and firefly algorithm
(Inst Engineering Technology-iet, 2019-11-19)
Deregulation in the electrical industry has led utility companies to ensure high quality of power supply at the customer side. It is of utmost importance for utility companies to operate at maximum efficiency and minimise ...
