Optimal capacitor placement in radial distribution systems using teaching learning based optimization

The conventional power system is going through a paradigm change towards smart grid Phasor measurement units (PMUs) have emerged as the edifice for information technology related to wide-area monitoring systems (WAMSs) for power system monitoring, information communication, and control purposes The PMUs require communication links for a complex interconnected power grid, and proper spatial coordination plays a vital role for wireless communication network Geographical information system (GIS) provides a rich set of functions to analyze the power network incorporating geospatial features This paper investigates the impact of topological attributes on commissioning of wireless communication network for PMUs incorporating GIS aided analysis and to optimize one of the PMU location as main control station This will not only serve for monitoring automation purposes, but will also ensure control automation Case studies related to the eastern grid of India corroborate the efficacy of GIS-aided wireless communication for linking PMUs

Communication Feasibility Analysis for Smart Grid With Phasor Measurement Units

Much of the research has been focused on developing the optimization techniques, varying from classical to nontraditional soft computing techniques, to solve the distribution system planning problem. Most of the methods preserve the distinctions and niceties, but dependent on complex search algorithm with a lot of convergence related issues that require more time to reach a firm conclusion at planning stage. This paper proposes a simple direct solution that significantly reduces the inherent difficulties of finding the solution and ensures optimum solution at the same time. Moreover, the concept of principle of optimality is effectively used to make the proposed technique more computationally efficient and useful. The effectiveness of the developed planning technique has been verified with different test cases.

A Direct Approach to Optimal Feeder Routing for Radial Distribution System

Improved radial load flow method

A new method for optimal feeder routing in radial distribution system planning has been reported in this paper. This method harnesses the efficacy of the bacterial foraging technique for solving combinatorial optimization problems with faster convergence and enhanced probability to achieve a global optimum solution of the distribution planning problem. In this new planning method, bacterial foraging technique is used in a different way so that it does not require tuning of all parameters. The planning algorithm provides optimal feeder routes to connect the load nodes. The result of test cases reflects the potential of this new planning technique in optimizing the network structure.
