A coordinated phase shifting control and remuneration method for a zonal congestion management scheme

摘要

This work presents a methodology for the phase shifter optimization which leads to economic benefits in congestion management. The tap range of each phase shifter is split into two parts: one part is a range reserved to ensure a given MW margin on each interconnection and the remaining part is used to compute a tap position for each phase shifter such that the overall economic benefit is maximized. The phase shifter owners can be remunerated in proportion to their contribution to the increase of the overall benefit due exclusively to the optimal phase shifting. This twofold phase shifter control and remuneration mechanism is integrated to a zonal congestion management scheme which is particularly efficient to manage the inter-area congestions of a grid composed of independent areas, each one responsible for its internal congestions.
