Stability analysis of the DC-DC power electronic system is analyzed in this paper using a G-parameter approach. For demonstration boost converter cascaded with the hybrid switched capacitor converter considered as an example. The boost converter is acting as the bus converter, 42 V bus, while the switched capacitor converter is the point of load converter. The two converters are provided with voltage-mode and peak-current-mode controllers, respectively. Converter two-port G-parameter network models are developed and then stability of the cascaded system has been analyzed. Cascaded system interaction effects, (i) source converter power handling capability with switching load, and (ii) load converter interfacing capability with bus converter, are analyzed. Simulation and experimental results are provided for verification purpose.

This paper presents optimum required rating of series and shunt flexible ac transmission systems controllers for EHVAC long transmission lines. This is achieved by computing `optimum compensation requirement' (OCR) for different loading conditions of EHVAC transmission systems. The OCR enables improvements to be made to the system loadability, total compensation requirement, line voltage profile and efficiency of power transmission. Two schemes of locating FACTS devices in long distance EHV transmission lines is discussed. In the first scheme, an UPFC of equal rating series and shunt compensator is connected on both ends of the line. In the second scheme SVC of equal rating is connected on both ends with a TCSC at the middle of the same line. For each scheme, requirement of series compensation Mvar, shunt compensation Mvar, Voltages (Vmax, Vmin), total Mvar requirement, Efficiency for surge impedance load is calculated and presented. The results are reported for line operation at surge impedance loading and a line angle of 30deg, chosen from the point of view of stability for voltage levels of 500 kv, 760 kv and 1100 kv under different operating conditions.

Conventional electric distribution systems are radial in nature, and are supplied through a main source. These networks have a very simple protection system which is usually implemented using fuses, re-closers, and over-current relays. Recently, great attention has been paid to applying distributed generation (DG) throughout electric distribution systems. Presence of such generation units in a network, leads to losing coordination of protection devices. Therefore, it is required to have an algorithm in hand which is capable of protecting distribution systems that include DG, through diagnosis and isolation of occurred faults. In this paper, a new approach for protecting of distribution networks in presence of DGs will be presented. The algorithm is based on dividing an existing distribution network into several zones; each of them is capable of operating in island operation. The proposed scheme has been implemented on some part of a real distribution network in Shiraz which is a large city in Iran and performance of the proposed scheme is tested on it. For simulating the distribution network and for implementing the relay algorithm, DIgSILENT Power Factory 13.2 and MATLAB are used respectively.
传统的配电系统本质上是径向的，并通过一个主电源供电。这些网络有一个非常简单的保护系统，通常使用熔断器、再闭合器和过流继电器来实现。近年来，分布式发电在配电系统中的应用受到了广泛的关注。在电网中存在这样的发电机组，会导致保护装置失去协调。因此，需要有一种能够通过诊断和隔离发生的故障来保护包括DG在内的配电系统的算法。本文提出了一种新的配电网络保护方法。该算法基于将现有配电网划分为几个区域;每一艘都有能力进行孤岛作战。该方案已在伊朗大城市设拉子的部分实际配电网中实施，并对方案的性能进行了测试。配电网仿真和继电器算法实现分别使用了DIgSILENT Power Factory 13.2和MATLAB。

Voltage profile at different nodes in the power system is affected greatly by the variations in load and generation profiles during normal and abnormal operating states. Under-voltages impact adversely on the system voltage stability margin and bulk power carrying capacity of transmission lines, which may lead to steady state or dynamic voltage collapse phenomenon. In order to avoid these circumstances the power utility operator in the control center will have to re-dispatch the reactive power control devices. The reactive power control devices are generators, tap positions of on-load tap changer of transformers and shunt capacitors. In this work the effect of changing reactive power control variables has been tested on Kerala grid consisting of 171 buses modeled in power world simulator. A genetic algorithm based approach to the optimization of reactive power and voltage profile improvement and real power loss minimization is also presented. The feasibility and effectiveness of the developed genetic algorithm is tested on a sample 9-bus system.

This paper introduces a new kind of optical current transducer and its application in measuring high voltage DC and AC in power system. To solve the long-term operating stability and the steady state metering accuracy which influence the practical course of OCT, this paper presents a new method which combines the lock-in amplifier in slight photo-electric signal detection and a new higher stability sensor, introduces the principle and the design of the optical sensor on solenoid collecting magnetic field, and analyzes the characteristics of signal and noise in OCT. This paper also describes the principle and the performance of the lock-in amplifier and its application in OCT in order to improve the output SNR. The test results indicate that under the steady state metering accuracy has already reached class 0.2, the long-term stability has improved, and the designed OCT has achieved the requests in power system.

This paper is about a study on inverter control of a voltage source converter based high voltage direct current (VSC-HVDC) transmission system. An inverter model has been developed for the purpose of system control and stability analysis. The VSC-HVDC system is the exclusive power supply to a passive load in this study, and the control objective is to obtain a constant sinusoidal output voltage under load variations. State space equations are derived to obtain the root loci, and to analyze the system stability. The influence of the circuit parameters on the system stability is investigated using the root loci. Results obtained from the simulation studies using EMTDC/PSCAD have verified the theoretical model and the proposed control method.

Implementation of particle swarm optimization (PSO) application for solving the optimization problem in the field of electric power system is proposed. PSO is a powerful tool for optimizing multidimensional discontinuous nonlinearity problems. The optimization problem in power system like minimization of energy capacity of a dynamic voltage restorer is identified and analyzed in the proposed work. The growing interest in power quality has led to a variety of devices designed for mitigating power disturbances, primarily voltage sags. Among several devices, a dynamic voltage restorer (DVR) is a novel custom power device proposed to compensate for voltage disturbances in a distribution system. The compensation capability of a DVR depends primarily on the maximum voltage injection ability and the amount of stored energy available within the restorer. A novel PSO based phase advancement compensation (PAC) strategy is proposed in this work for optimizing the energy storage capacity of the DVR in order to enhance the voltage restoration property of the device. The proposed algorithm is tested on a sample three phase system for various levels of sag in a particular phase. The proposed algorithm identifies the required value of phase advancement angle corresponding to minimum power injection from the energy storage element such as a capacitor or a battery. The results of swarm intelligence based DVR are compared with the conventional DVR techniques and is found encouraging.

Price forecasting has been at the center of intense studies since the introduction of competition in electricity industry. Price forecasts are a fundamental input to an energy company's decision making and strategy development. The present approach is an attempt to forecast day-ahead electricity prices using time series of historical data. A combination of weighted nearest neighborhood and wavelets is used to forecast the next day electricity prices. The methodology is applied to historical data pertaining to California electricity market. The performance of the method is discussed with mean absolute percentage error (MAPE).

The paper proposes a binary version of the differential evolution algorithm and then solves the transmission and voltage constrained unit commitment using it. The proposed algorithm uses binary coding of the selection variables and implementing OR/XOR/NOT type Boolean logics on variable strings. The inclusion of the ramp rate, transmission/voltage constraints ensure the feasibility of the schedule. The solution algorithm has been found to be capable of finding the optimum/near optimum solution.
