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!

PO103: Solving intermittency - designing renewable energy plants for constant power output

Jose Pedro Blasques, Head of LCoE Performance, Vattenfall

Abstract

The intermittency of the wind and solar power output is often referred to as one of the main impediments to achieve 100% renewable energy systems. Using battery energy storage systems (BESS) it is possible to shift the generation profile over time and eventually modulate the power output to meet specific demand profiles and dispatchability requirements. This work analyses the technical and economical feasibility of renewable energy plants designed to deliver constant power output combining wind and solar power, and a BESS. A large number of plant designs are assessed in HyDesign, a software for design and optimisation of renewable energy plants combining wind, solar, BESS, and electrolysers. HyDesign simulates the operation of the plant and optimises the energy management system (EMS) to meet different types of objective functions and constraints. In this work, the EMS is designed to maximise the number of hours the output production meets a given set point. The design variables are the output set point, wind and solar capacity, and the energy storage's power and capacity. Starting from a wind and solar farm system, a BESS is then added. Results are shown where intermittency is progressively reduced, i.e., where the number of hours the plant produces the specified constant power output is progressively increased. LCoE values are presented for concepts delivering constant power from around 20% to almost 100% of the time. Results show that it is possible to design renewable energy plants that deliver a constant power output within duration and LCoE ranges that are comparable or lower than other traditional so-called base-load energy sources like nuclear and gas power plants. This ability to modulate the power output of renewable energy plants within economically viable ranges, is a potentially significant step towards achieving 100% renewable energy systems.
