Abstract
Dette speciale foreslår en ny kraftværks-topologi, der kombinerer en vindpark med en protonbyttermembran (PEM) elektrolyse til brintproduktion og -lagring samt en forbrændingsturbin-generator. Målet er at koordinere enhederne, så anlægget kan levere konstant elektrisk effekt og følge ordrer fra transmissionssystemoperatøren (TSO), så det vindbaserede system fra nettets perspektiv opfører sig som et konventionelt kraftværk. Arbejdet adresserer vindens intermittens og netkrav og udvikler detaljerede modeller af PEM-elektrolysatoren (brintproduktionshastighed, elektrolytiske poler, membran, spændingsrespons, tanke og elektrisk grænseflade), vindparken og vindhastighed, en forbrændingsturbin, en STATCOM til spændingsstøtte, det omgivende elsystem og et elpris-signal. En koordineringsstrategi udformes til at fordele effekt mellem brintproduktion, lagring og turbinproduktion; den omfatter logisk styring og båndpasfiltrering og håndterer ekstreme driftstilstande som ødrift og dæmpning af spændingsfluktuationer. Et MATLAB/Simulink-simuleringsmiljø implementeres, og casestudier undersøger konstant-effekt drift, efterlevelse af tidsvarierende energikrav, ødrift, spændingsdæmpning og profit-orienteret drift. Uddraget rapporterer ikke kvantitative resultater, men simuleringerne anvendes til at verificere funktion og vurdere ydeevne af det foreslåede koncept.
This thesis proposes a novel power-plant topology that combines a wind farm with a proton exchange membrane (PEM) electrolyzer for hydrogen production and storage and a combustion turbine generator. The goal is to coordinate these units so the plant can deliver constant electrical power and track dispatch orders from the transmission system operator (TSO), allowing the wind-based system to behave like a conventional generator from the grid's perspective. The work addresses wind intermittency and grid compliance, and develops detailed models for the PEM electrolyzer (hydrogen production rate, electrochemical poles, membrane, voltage response, tanks, and electrical interface), the wind farm and wind speed, a combustion turbine, a STATCOM for voltage support, the surrounding power system, and an electricity price signal. A coordination control strategy is designed to allocate power between hydrogen production, storage, and turbine generation; it includes logic control and band-pass filtering and addresses extreme operating conditions such as islanded operation and voltage fluctuation mitigation. A MATLAB/Simulink simulation environment is implemented, and case studies explore constant-power operation, following time-varying energy requirements, islanded mode, voltage mitigation, and profit-oriented operation. The excerpt does not report quantitative results, but the simulations are used to verify functionality and assess performance of the proposed concept.
