Application of a New Dispatch Methodology to Identify the Influence of Inertia Supplying Wind Turbines on Day-Ahead Market Sales Volumes

Power system inertia is an essential part of grid frequency control. The number synchronously connected machines, which inherently provide inertia, decreasing due to the transition renewable energies. Conventional generation units are being replaced by via converters. Some power systems already suffer from too little inertia. Hence, a valuable yet non-traded commodity. A day-ahead dispatch methodology secure was developed and applied assessed in this work. Day-ahead market data combined Republic Ireland Northern used. If superimposition sell buy bids results insufficient algorithm applied. In price order, non-inertia-providing get following merit order. iterative process repeated until sufficient system. provision synthetic wind turbines considered process. costs for additional stored kinetic energy time periods scenarios result ranging 1.02 4.49 EUR/kgm2.
