This results in a decrease in resources available for frequency regulation, inertia, and short-circuit power, which must be compensated for with alternative resources and solutions. Assessing the adequacy of flexibility resources for the stability of the power system is therefore essential: this document presents three related activities.<\/p>\n<p>The first activity involves updating the tool for mono-zonal (single-bus equivalent) assessment of resources for conventional frequency regulation (slow regulation: primary, secondary, and tertiary) and short-circuit power. The tool has been updated for multi-zonal analysis of active power reserve and has been prepared for multi-zonal developments concerning short-circuit power. Application to a national scenario for 2030 has revealed potential issues in meeting secondary and tertiary reserve requirements due to the limited availability of thermoelectric generation, based on significant decarbonization assumptions.<\/p>\n<p>The second activity focuses on the evolution of the \u201cSeTA\u201d (SErvizi innovativi: Tuning Automatico) procedure for optimizing ultra-fast frequency regulation services. A new iterative approach has been implemented to improve accuracy in identifying equivalent output-error models of the power system used for sizing the necessary regulation quantities. The new approach, even in the identification phase, considers the contribution of innovative regulations. Application to a 2030 scenario for the Sardinian system highlights that fast primary regulation is crucial. Synthetic inertia is shown to be necessary if the three new synchronous compensators planned are not implemented.<\/p>\n<p>The third activity involves defining specifications for an integrated analysis platform for slow and ultra-fast frequency regulation resources. In light of the developments achieved in the above-calculated procedures, automating the acquisition of preliminary market simulation results for analysis appears to be a priority.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":173688,"id":173688,"title":"21008890","filename":"21008890.pdf","filesize":4757880,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2022\/11\/21008890.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/valutazioni-sulla-stabilita-di-frequenza-e-sui-requisiti-di-inerzia-e-potenza-di-cortocircuito-nel-sistema-elettrico-italiano-modelli-e-strumenti-integrati\/attachment\/21008890\/","alt":"","author":"93","description":"","caption":"","name":"21008890","status":"inherit","uploaded_to":173687,"date":"2022-11-21 09:59:59","modified":"2022-11-21 09:59:59","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-12-31","autori":"A.
