Embodiment Construction

[0020] The detailed description, taken with the drawings, is intended to illustrate preferred embodiments of the invention and is not intended to represent the only forms in which the invention can be practiced. It should be understood that the same or equivalent functions can be realized by different embodiments, all of which are included in the spirit and scope of the present invention.

[0021] The present invention provides a method and system for congestion management in a power transmission network. The power transmission network includes at least one power generation unit and at least one power flow control device (PFD). The method involves determining a reference generation schedule for a generating unit, then formulating an optimization problem, including an objective function and a set of constraints, and based on the design of the reference generation schedule, power flow in the power transmission network, regulation bids, the actual generation schedule, and the PFD...

Abstract

The present invention is concerned with a method and system for managing congestion in an electrical transmission network. The electrical transmission network includes Power Flow Control Devices (PFDs) that adjust the transmission capability of the electrical transmission network. The method includes determination of a reference generation schedule followed by setting up of an objective function based on the reference generation schedule, a power flow in the electrical transmission network, bids for regulation, an actual generation schedule, and set points of PFDs. An optimisation problem is solved to minimize the objective function for a set of decision variables and the set of decision variables is applied in order to minimize congestion cost in the electrical transmission network.

Description

technical field [0001] The present invention relates to managing power flow in a power transmission network, and more particularly to congestion management in a power transmission network comprising parallel transmission paths and a power flow control device for adjusting power flow distribution on the transmission paths. Background technique [0002] Electrical energy consumption has increased many-fold over the past decades. Electric energy is widely used in communication, entertainment, business and other fields that mainly rely on electric energy for operation. To transfer electrical energy from a source of generation to a source of consumption, a power distribution system or grid is employed. These grids, also known as electrical transmission networks, provide electrical energy to households, businesses, manufacturing plants, and the like. [0003] Due to the large amount of power being transferred, it is very difficult to manage the flow of power transmitted through...
