Contingency Ranking

Security assessment of a power system is very important function to detect any violation in the system and to ensure secure operation of the system in deregulated environment. Contingency ranking is the process of indexing the possible contingencies of system on the basis of their severity. The contingencies of higher ranking are further analyzed for detailed analysis. The contingencies based on the real power flow and the voltage deviations should be dealt simultaneously for better ranking. The paper presents fuzzy approach to combine ranking based on MW and Mvar losses and a new rank list is prepared. The proposed approach is tested on IEEE-30 bus test system.

Reducing the loss of real power and maintaining the system voltage under limits are challenging and major problems in a power system network. Thus, it is desired to adapt an effective method that could clear up these problems or reduce it to the minimal level. Controllers with FACTS, for instance Unified Power Flow Controller (UPFC) can effectively enhance the various power system parameters. This paper proposes a new meta-heuristic algorithm known as firefly algorithm (FA) which is used to select the optimal location and sizing of UPFC , which minimizes the total real power losses and to maintain the voltage under limits, there by maintaining the power system stability. On the IEEE 14 bus system the performance of the proposed method is examined by taking into account the 125%, 150%, 175% and 200% overloading cases.

This paper focuses on three key issues of the power system that is stability enhancement, minimization of real power losses, and improving voltage profile of the buses by placing the Unified Power Flow Controller (UPFC) to the best location in WSCC 3 machine 9 bus system. The comparison between with and without UPFC is carried out to prove that UPFC enhances the stability of the multi machine power system. In this paper the best location of the UPFC is recognized by Power Flow Analysis. Eigen Value Analysis and Continuation Power Flow (CPF) is employed to show the performance of UPFC for stability enhancement. The analysis is carried out using Power System Analysis Toolbox (PSAT) software.

This paper proposes an optimization technique for distributed generation (DG) sizing in power system. The DG placement was done through Loss Sensitive (LS) technique to determine the suitable locations. The LS index is calculated such that the change in power losses is divided with generation increment and a rank of buses is obtained to identify the suitable locations for DG placement.  Subsequently, a meta-heuristic algorithm, known as Firefly Algorithm (FA) was run to obtain the optimal size or capacity of the DG. The installation takes into consideration the aspect of voltage stability in terms of total real power losses and voltage profiles to be improved in the distribution system. Based on the experiment, the real power losses and voltage profiles were improved significantly as a result of the DG placement. In addition, the installation could prevent the power system from collapse as the reactive loading was increased to maximum.

Power quality is a comprehensive term used to estimate the caliber of the power system in delivering high-grade supply and is an interesting study to ensure customer satisfaction. DSTATCOM is one of the custom power devices used to refine the power system parameters especially to ensure that the source current contains acceptable harmonic limit. Parallel connected DSTATCOM is a topology with two parallel DSTATCOMs connected to the point of common coupling for harmonic reduction in source current and improving the power quality. Each of the two parallel DSTATCOMs has its individual DC storage source to adjust the real power deficit to the system (during load transients). This paper presents a common DC-Link fed parallel DSTATCOM topology for power quality improvement. Unlike the conventional parallel DSTATCOM topology, common DC-Link fed parallel DSTATCOM topology employs only one DC-Link source reducing the number of DC sources, cost and increases reliability. The single DC storage source adjusts the real power deficit to the system. In this paper, IRP control methodology delivers the control pulses to parallel DSTATCOM. The proposed system is tested with variable and constant load operations and the results are presented using MATLAB/SIMULINK software.
