Optimization and Validation of Distributed Generation Integrated Load Flow Scheme for Congestion Management of Interconnected Transmission Systems | Chapter 4 | Research and Developments in Engineering Research Vol. 9

 In reaction to scheduled or unscheduled disruptions, energy supply institutions extensively employ delivered generators (DG) to fulfil raised power demands. The expansion of broadcast and distribution networks, coupled with line interruptions, donates significantly to transmission line blockage within pertain systems. Addressing and mitigating blockage is essential for ensuring the reliable and adept operation of a power network. This branch explores the potential of delivered generation (DG) to alleviate blockage within interconnected broadcast systems. It places significant importance on devising a dependable approach to decide the optimal positions and sizes for integrating local generators to responsibility congestion, as it is a crucial necessity. The research aims to develop a straightforward and reliable strategy for the installation and sizing of DGs within a broadcast line system, utilizing capacity flow analysis. The initial reasoning is conducted on the 14-transport IEEE system to identify limits for assessing congestion asperity and determining the ideal DG locations and sizes. Load flow algorithms in ETAP program are utilized to assess capacity flows under various line interruption scenarios in the 14-bus IEEE order. The results indicate that the percentage breach of the system is a critical limit for evaluating blockage in interconnected systems. The study further checks the application of two indices, the Severity Index (SI) and Sensitivity Factor (SF), to recognize the optimal DG placement and volume for congestion relief. A reliable algorithm established these indices is proposed to guide DG installation and sizing decisions. This methods is grounded in whole indices and relies on load flow study. The proposed algorithm offers expeditious and accurate simulation results accompanying minimal approximations, ensuring inclusive optimal resolutions within a shorter imitation time and enhanced union probability, leveraging a mathematical approach. The practicability of this projected methodology for determining optimum DG placement and quantification in blockage solutions is assessed utilizing a practical pertain bus system inside the Kerala grid. This methodology is movable and can be adopted by broadcast system operators in related connected wholes worldwide. It effectively labels severe congestion cases and advises the best locations and sizes for DGs to survive congested feeders inside the grid system. Finally, the study of system losses for differing DG penetration scenarios through load flow study validates the acquired results.
