Thesis Outline

 

This paper proposes a new methodology for solving the problem of State Estimation in Electricity Distribution Systems. The main contribution is the use of Energy as a pseudo-measure under the condition of maximum demand in those of nodes of the network in which the client-transformer relationship is available. The objective function is to minimize the weighted quadratic error subject to the non-linear equations of voltages linked to the injected currents in accordance with the Kirchoff Laws, developed in reference [1]. The methodology was successfully applied to the IEEE test networks of 4, 37 and 123 nodes. The results obtained are compared and validated with the classic treaty of state estimation based on the nodal power equations developed in [2] and [3]. Finally, a Sensitivity Analysis is carried out via the application of Monde Carlo's Technique, modeling the vectors of measurements and pseudomedidas as independent random variables belonging to normal probability distributions.
