Renewable Energy Source A neural network based speed control of a linear induction motor drive http://works.bepress.com/dr_adel72/56 http://works.bepress.com/dr_adel72/56 Sat, 11 Dec 2010 05:04:17 PST In this paper, a general regression neural network (GRNN) based controller is used to control the speed and thrust output of the linear induction motor drive. The field orientation principle is used to asymptotically decouple the motor speed from the secondary flux. The idea of model predictive control technique is used for the training of the proposed controller. The motivation for using this control strategy for training the GRNN based controller is to reduce the effect of the uncertainty due to motor parameters variation and load disturbance. This newly developed design strategy combines the advantage of the neural networks and MPC control techniques to provide robust performance and leads to a flexible controller with simple structure that is easy to implement. Digital simulations have been carried out to validate the effectiveness of the proposed scheme. The results of the proposed controller are compared with the corresponding one using the traditional PI controller. The results show that, the proposed technique has the ability to control successfully the speed and thrust of the linear induction drive in face of the motor parameters variation or load force disturbance.

Electrical Machine Simulation studies on ECS application in a clean power distribution system http://works.bepress.com/dr_adel72/55 http://works.bepress.com/dr_adel72/55 Sat, 02 Oct 2010 07:05:16 PDT Dealing with power distribution system became one of the most important arts in the field of power system, especially in the rapid increase of the distributed generation (DG) penetration to the distribution level which is a vital and important part of the entire power system. In this paper, a very special power distribution system with a unique deployment of distributed generation, such as, photovoltaic and wind generation has been studied. Energy storage system is utilized to play the main role to control the system’s power quality and the system frequency, as load following operation (LFO) and automatic generation control (AGC), respectively. In this paper, a working criterion has been introduced followed by a case study focuses on two important conditions, one of them when the proposed system is connected to the electrical grid (upper system) and the other one when the system is completely islanded. In both cases, the crucial usage of the ECS gives a concrete result which made the system fully recommended to be applied in real life.

Elbaset Renewable Energy Source Genetic Algorithm Based Optim-al Sizing of PV-Diesel-Battery System Considering CO2 Emission And Reliability http://works.bepress.com/dr_adel72/53 http://works.bepress.com/dr_adel72/53 Sat, 14 Aug 2010 08:39:37 PDT The reliability system concern and CO2 emission reduction are still the main targets of optimization problem in the hybrid generation system components. This pa- per utilizes Genetic Algorithm (GA) method to determine the optimal capacities of PV system, battery bank and diesel generator (DG) unit according to the minimum cost ob- jective functions that relate to these two factors. In this study, the cost objective function includes the annual capital cost (ACC), annual operation maintenance cost (AOM), an- nual replacement cost (ARC), annual fuel cost (AFC), annual emission cost (AEC) and annual customer damage cost (ADC). The proposed method has been tested in the hybrid power generation system located in East Nusa Tenggara, Indonesia (latitude 09.30S and longitude 122.0E). To show the effectiveness of this method, three different crystalline Silicon PV module technologies: ASE-300 (mc-Si based EFG), Kyocera KC-120 (mc-Si based wafer) and AstroPower AP-120 (thin-film Si) were used. Simulation results show that the optimum configuration can be achieved using thin-film Si technology of PV mod- ules, battery banks and diesel generator unit with capacities of 139,250×120W, 5×5MWh and 12MW, respectively. This study also reveals the importance of PV and battery sys- tems in the hybrid generation system from economical, reliability and environmental point of views.

The system consists of a wind farm for electricity generation and an electrolyzer to produce hydrogen for a filling station. A computer program has been developed in MATLAB for simulating the operation and control of the integrated system. Energy balances and hydrogen flow balances are calculated for each time step based on a system model and the specified control strategy. The input of this program are hourly wind speed, characteristics of wind turbine generators, hourly load demand, maximum grid capacity, rated power of electrolyzer, and minimum operating power of electrolyzer. The hydrogen produced will be supplied to a filling station where local vehicles can be filled. Hydrogen production is evaluated and the number of cars served per year is estimated.

Renewable Energy Source Modeling and Computer Simulation of Fault Calculations for Transmission Lines http://works.bepress.com/dr_adel72/50 http://works.bepress.com/dr_adel72/50 Thu, 07 Jan 2010 05:34:17 PST Calculation of transmission line faults has a fundamental importance in the fault detection, classification, and location determination of faults in transmission line. This paper presents a proposed computer program based on Matlab software to calculate all ten types of shunt faults that may occur in a transmission line. Various fault scenarios (fault types, fault locations and fault impedance) are considered in this paper. The inputs of the proposed program are line length, source voltage, positive, negative and zero sequence for source impedance, line charging, and transmission line impedance. The output of the algorithm is used to train an artificial intelligence networks to detect, classify and locate transmission lines faults. Simulation results have shown the effectiveness of the algorithm under the condition of all types of shunt faults.

Most of optimization method just consider only from economical point of view. This paper presents complete optimization method involving of cost, reliability and pollutant emission into optimization process. The reliability level is analyzed using basic probabilistic concept in order to find loss of load probability (LOLP). This value is then used to determine the customer damage cost due to electricity interruption. Meanwhile, CO2 emission as an indicator of pollution is calculated to determine the annual emission cost (AEC). By considering both reliability level and CO2

emission, the optimization results do not just show economic merit but will satisfy both of reliability level

and environmental issue.

Power Point Presentation Impact of Interconnection Photovoltaic/Wind System With Utility on Their Reliability Using a Fuzzy Scheme http://works.bepress.com/dr_adel72/42 http://works.bepress.com/dr_adel72/42 Sun, 19 Jul 2009 07:48:14 PDT Reliability analysis has been considered as an important step in any system design process. a reliable electrical power system means that the system which having sufficient power to feed the load demand during a certain period or in other word, having small Loss of Load Probability (LOLP). LOLP is defined as an expected fraction of load not met by its needed power from electrical power system during its lifetime. Photovoltaic (PV) / Wind Energy System (WES) hybrid electric power system (PV/WES HEPS) differs considerably from the utility grid (UG) in their performance and operating characteristics. With the interconnection of PV/WES as a HEPS into the UG, the fluctuating nature of the energy produced by these systems have different effect on the overall system reliability than the energy produced by UG. Therefore, this paper presents a complete study from reliability point of view to determine the impact of interconnecting PV/WES HEPS into UG. Four different cases have been investigated. A comparative study between these four different cases have been carried out from reliability point of view. The overall system is divided into three subsystems, containing the UG, PV and WES. The generation capacity outage table has been built for each of these subsystems. These capacity outage tables of PV and WES are calculated and updated to incorporate their fluctuating energy production. This paper presents also a fuzzy logic technique to calculate and assess the reliability index for each case under study. The fuzzy logic has the following design parameters:- type-Sugeno, gauss membership functions, 144 linear terms for output membership functions.
