This paper has developed a novel multiobjective function for optimal sizing and sitting of Distributed Generation (DG) units and capacitor banks in simultaneous mode to improve reliability and reduce energy losses. The proposed function consists of four objectives: Cost of Energy Not Supplied (CENS), System Average Interruption Duration Index (SAIDI), costs of energy loss and investment. A nove...

The paper introduces a novel, scalable control allocation (CA) formulation for active capacitor balancing of the Modular Multilevel Converter (MMC). is obtained by introducing converter arm model that also and accommodates an MMC with any number phases submodules (SM). CA algorithm involves fast real-time minimization error cost function formalized as linear programming (LP) quadratic (QP) prob...

This paper represents an effective method for optimal placement of DG and capacitor in distribution system. The main objective is to reduce the power losses in the system by placing capacitor and DG of optimal size and at optimal location. Distribution system connects the high voltage transmission system and low voltage side, hence it is necessary to keep the system at minimum losses for making...

The installation of shunt capacitors in primary distribution electrical networks can effectively reduce energy and peak power losses, while improving voltage profile. Economic and operational benefits depend mainly on the number, locations and sizes of the capacitors installed. Several approaches devoted to this problem have been reported in the literature. However, most of them adopt some unre...

Many nature inspired meta-heuristic algorithms have been attempted for reactive power compensation of radial distribution feeders. In this paper, we introduce and implement a novel accelerated particle swarm optimization technique. Results of the proposed approach are compared with previous methods to show the superiority of the proposed method using three actual distribution feeders (of 9 bus,...

This paper presents a genetic algorithm based approach for solving security constrained optimal power flow problem (SCOPF) including FACTS devices. The optimal location of FACTS devices are identified using an index called overload index and the optimal values are obtained using an enhanced genetic algorithm. The optimal allocation by the proposed method optimizes the investment, taking into ac...

A switchable operational amplifier (op-amp) that uses a switched capacitor integrator has an advantage such as low power consumption and wide gain-bandwidth product. The power reduction is achieve by apply switching samples at the input and output capacitors. These capacitors can be otherwise would contribute in increase in power consumption. During the first phase of the sample the opamp compl...

Properly sized capacitor banks are connected across induction motors for several reasons including power factor correction, reducing distortions, increasing capacity, etc. Total harmonic distortion (THD) and power factor (PF) are used in such cases to quantify the improvements obtained through connection of the external capacitor banks. On the other hand, one of the methods for assessing the mo...
