V magistrski nalogi je predstavljen predlog zasnove poslovno-informacijske platforme za obvladovanje in spremljanje primarne regulacije frekvence v slovenskem elektroenergetskem sistemu (EES). Model platforme je zasnovan s pomočjo ogrodja TOGAF, na osnovi politik in procesnih modelov podjetja ELES, metodologije ITIL in principa storitveno usmerjene arhitekture (SOA). Za opis arhitekture platforme smo uporabili opisni jezik Archimate 2.0, primer konstrukcije podpornega procesa pa smo opisali z notacijo opisnega jezika BPMN. Opis arhitekture platforme je zajet v domenah motivacije (vizija in strateški vidik načrtovanja), poslovnih procesov, aplikacijskih rešitev, tehnologij ter implementacije in načrtovanja. Celoten koncept arhitekture platforme je modeliran z orodjem Enterprise Architect (Sparx SystemsTM), študija primera podpornega procesa je izvedena z orodjem za upravljanje informacijskih storitev EasyVistaTM. Predlog modela platforme je predstavljen z več zornih kotov in perspektiv, glede na zanimanja in dileme deležnikov v posameznih domenah arhitekture platforme. Izbrani način opisa in predstavitve platforme smo izbrali zaradi zagotavljanja preglednosti in »sporočilnosti« (gostote informacij) modela, saj platformo sestavlja veliko elementov z različnimi medsebojnimi relacijami, ki so pomembne za realizacijo zahtev naročnika. Odgovor na vprašanje obvladovanja in spremljanja primarne regulacije frekvence v slovenskem EES podaja koncept storitve točne regulacije frekvence (TRF). Zanj je značilen premik od modela kolektivne plačljive storitve k modelu individualno plačljive storitve in uporaba statike v vseh obratovalnih stanjih agregatov. To zagotavlja želen obseg izvajanja storitve in enakomerno porazdelitev regulacijskega obsega moči med posameznimi agregati, pri čemer vlogo nosilca informacij za porazdelitev obsega moči med agregati prevzame kar omrežna frekvenca EES. Opisani fizikalni princip prenosa informacij med posamezni ponudniki storitve TRF deluje, čim je prisotna napetost v sistemu in je popolnoma neodvisen od ITK storitev, kar zagotavlja še toliko večjo robustnost koncepta. Namen zasnove želene storitve je v zagotavljanju čim večje avtomatizacije podpornih procesov ter obvladovanje sprememb modela, kar omogoča učinkovito usklajevanje poslovno-informacijske platforme z zahtevami poslovnega okolja.

• Title: PLATFORM FOR MANAGEMENT AND MONITORING OF PRIMARY FREQUENCY CONTROL IN ELECTRIC POWER SYSTEM

Abstract

The thesis presents the design proposal of Enterprise Architecture model that captures platform details for management of Load Frequency Control in Slovenian Power Grid. The design of platform architecture follows a well-established general IT management practices and principles like ITIL, TOGAF-framework, Service Oriented Architecture (SAO) and specific ELES policies and process models. Archimeta 2.0 notation was used for description of platform architecture, while BPMN notation was used to capture business process concepts. Platform architecture model cosists of following domains: Motivation Layer (Vision & Strategy), Business Layer, Application Layer, Technology layer and Implementation & Migration layer. The concept of platform architecture was modelled with Sparx System Enterprise ArchitectTM, while ITSM tool EasyVistaTM was used for implementing case study of the support service. Proposed Exact-Load Frequency Control (E-LFC) platform architecture model is represented with variety of views and model viewpoints to successfully communicate interests and concerns to stakeholders. The modelling approach was chosen in order to ensure transparency and “information density” of proposed architecture model as it is composed of a large number of interconnected elements and its relations that are important for the realization of the stakeholder’s requirements. Proposed concept of Exact-Load Frequency Control (E-LFC) addresses current issues of Load Frequency Control in Slovenian Power Grid. It’s main characteristics are introduction of marker concept of E-LFC service and mandatory use of droop for all generators. This ensures target performance and joint contribution of generators to Primary Control Reserve of Control Area. Network Power Frequency acts as “Physical Service Bus” that communicates consistent Power Control Reserve contribution demands between affected generators of Control Area. The “Physical Service Bus” is ICT independent, which adds the robustness and reliability to proposed concept of Exact-Load Frequency Control (E-LFC). The purposed Enterprise Architecture platform is aimed at automatization of supported services and long-term management of changes while allowing business flexibility and adaptivity.
