Techno-economic analysis of global power quality mitigation strategy for provision of differentiated quality of supply

Abstract

This paper presents a comprehensive methodology for techno-economic assessment of power quality (PQ) mitigation solutions, both network-based and device-based, and proposes an optimisation-based PQ mitigation strategy for delivering differentiated PQ in networks integrated with renewable generation. The proposed strategy is based on the evaluation of financial losses due to several critical PQ phenomena, the cost of different mitigation solutions and the payback due to the adoption of particular solution. Furthermore, it accounts for different customers’ requirements and provides differentiated levels of PQ across the network. The simulation results present both the financial and technical benefits of the optimal mitigation scheme.
