Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO018: Equation-based load-flow calculation of an offshore wind farm
Julius Krah, Power system consultant, Vattenfall
Abstract
The first known parameters of a future wind farm is the planned power production and the distance from the nearest grid connection. The export system can consist of an overhead line, a land cable and a sea cable. Standard cables with different conductor cross-sections, voltage levels and number of parallel circuits have to be compared to find the most attractive business cases with respect to feasibility, cost, losses and compensation requirement. An interactive Python tool was developed for this topology. Focus is on simplicity yet accuracy. This paper presents the approach behind the tool. It shows the single line diagram with load flow results. At each cable section there is a transformer with tap changer and a shunt. Overhead lines and cables can be selected from a list of standard high-voltage cables. The high-voltage equipment ratings can be changed interactively, a device can be split into a number of equal parallel devices or disabled by setting its parameter values to zero. Different curves and plots can be created. Since the topology is known, the whole system is solved analytically instead of using iterative methods like the common Newton-Raphson method, which makes the tool accurate, robust and fast. All results agree with those of the same models in the commercial power system program PowerFactory, which models the line and cables with distributed parameters.
