Integrated Approaches to State Estimation and Monitoring in Modern Power Systems

Abstract

When paired with the findings of state estimation, the data obtained from monitoring metres enables utilities to identify regions with high demand or congestion, which in turn enables effective load management and control measures to be implemented. It is possible for utilities to monitor the performance of renewable energy sources thanks to the strategic deployment of monitoring metres. There are a number of obstacles that must be navigated in order to achieve optimal planning for monitoring metres and state estimates. The power distribution systems are the backbone of the energy supply. They ensure that the electricity is delivered from the transmission networks to the end users in an effective and dependable manner. The need of efficient monitoring, control, and optimisation is only going to grow more pressing as these systems continue to become more intricate and interdependent on one another. In the field of electricity distribution, optimal design of monitoring metres and state estimate methodologies has emerged as an important area of attention, with the goals of improving system performance, enhancing decision-making procedures, and ensuring the dependable functioning of distribution networks. Monitoring metres are an extremely important component in the process of collecting real-time data from several locations across the electricity distribution network. These metres give vital information on a variety of characteristics, including voltage levels, current flows, power quality, and performance indicators for the system. The information that is gathered from these metres is very useful for optimising the regulation of power flow, recognising irregularities in the network's behaviour, locating defects, and monitoring the network's behaviour. However, the positioning of monitoring metres in a strategic location is necessary in order to make the most of their usefulness and efficiency. The most effective method of planning for monitoring metres is identifying the points throughout the distribution system at which these metres may be installed in the most optimal places. Experimental experiments are carried out in order to verify the efficacy of the methods for improving power distribution via the optimisation of monitoring metres and state estimates.
