An Efficient Upgradation of STATCOM to PV-STATCOM and Result Estimation using SIMULINK

Power generation is a much discussed topic in research works recently. Power production from different renewable source were the most processed topic. There are large number of solar farms which produce heavy electricity throughout the world but the overall efficiency of those solar farms remain unutilized especially in morning and evening when the sunlight is at its minimum the power production is too low. The series of Photovoltaic Cells (PV) are responsible for power production which are connected with the grid. The solar power output is D.C which can be transformed into A.C by inverter injection in the production line. STATCOM is proposed system which is a device is coming from the sub categorization of FACTS. STATCOM is concentrated on voltage source transformer. It operates in accordance as rectifier and inverter is used to increase power transmission limits. It also has the feature of damping control. The overall gist of the system is we propose a PV-STATCOM control concept. We use MATLAB 2013a to develop a Simulink simulation of PV-STATCOM system. It will be a solar inverter which is voltage controlled and it has overall inverter properties too.

Evaluating Available Transmission Capability using PTDF and Generator Participation Factor

Congestion management in restructured power system is a major technical challenge for the power system engineers. For a congestion free power market , Available transfer capability(ATC) is to be enhanced. ATC is a measure of remaining MW transaction that can be carried out without violating the transmission limits. In deregulated market , change in load can be met by more than one generator of the system generator participation factor is a measure of amount of power contributed by the generator to satisfy the load.This paper proposes that in simultaneous power transaction generator participation factor can decide the ATC of the network and can also change the maximum amount of load sustained by the bus before causing congestion of the network For this coding is done in MATLB and results are verified on Power world Simulator software

Bees Two-Hive Algorithm for Optimal Power Flow

This paper presents bees two-hive algorithm for solving the optimal power flow (OPF) problem with various constraints. The objective of the proposed technique is to improve the quality solution of the conventional bees algorithm that minimize the total fuel cost subject to operational and physical constraints i.e. energy balance, generation and transmission limits including security constraints. The proposed methodology is tested on the IEEE 30-bus test system. The results obtained using the proposed approach are compared to GA, PSO, BA and other conventional. The comparison of quality solution with other algorithms confirms performance of proposed technique. Simulation results demonstrate that bees two-hive algorithm provides better results than other heuristic techniques.
