Distribution system congestion management through local flexibility market

Abstract

Congestion that is the increasing problem of many distribution systems can be resolved using the local flexibility market (LFM) as a market-based solution along with non-market-based solutions such as reactive power control, network reinforcement, coordinated voltage control etc. The objective of this study is to show how the market and non-market-based solutions can relieve congestion by designing and using a simulation environment. The idea of the study is to solve the congestion in distribution networks through LFM, non-market-based solutions, or a mix of those alternatives. To do so, the simulation environment enables us to analyse and understand the features of three scenarios associated with congestion management (CM). A deterministic optimisation algorithm in the distribution management system is used to select the best solution candidate for CM.
