Voltage Profile Optimisation for Weak Distribution Networks

چکیده
Recent advances in power electronic technology have seen the development of a range of converter based power compensation systems which have the potential to improve supply quality and increase line utilisation in weak distribution networks at relatively low cost. However, the interaction of these devices with the supply network has not been well documented. In this paper we investigate the steady-state performance of Voltage Source Inverter (VSI) devices connected in parallel to radial distribution networks for the purpose of voltage regulation, including DSTATCOM’s and active interfaces for Distributed Generation (DG) systems. An optimisation algorithm is developed to calculate the real and reactive power injection required to achieve an optimal voltage profile across the network for given injection locations and load conditions. Practical examples are used to demonstrate the application of this algorithm.
