Principles and tools of research of regionally isolated electrotechnical complex from the standpoint of system analysis

Renewable energy sustainability in terms of systems analysis

“…The above statement largely reflects the definition of a complex system given in GOST 22.2.04-2012 [10], and correlates with a number of definitions adopted in the world and domestic literature [11][12][13][14], including the concept of a complex technical system. The corresponding outline structural energy flowchart of RIETC CTS in terms of systems analysis is shown in Figure 1.…”

“…The functions of all components of RIETC and the RIETC itself as a whole are aimed at achieving the supersystem set goal or goals. The interaction and interdependence of the components of the RIETC proceeds through a system of external energy and non-energy interactions [12].…”

“…The corresponding outline structural energy flowchart of RIETC CTS in terms of systems analysis is shown in Figure 1. Were: Надсистема-Supersystem; ВНВ-ENI; ВЭВ-EEI; Цельнадсистемы -Supersystem goal; ИСЭ-IPSS; ЦельИСЭ -IPSS goal; РОЭТК-RIETC; ЭТКГ -ETGC (electrotechnical graphitization complex); ПЧ -FC (frequency converter); АКБ -AB (accumulator battery); Г -G (graphitization) Statement 1 leads to the need to use systems analysis (MSA) in the analysis and synthesis of ROETK CTS [12]. Optimization problems for ROETK CTS, using MSA, lead to the need for a weakly formalized choice of optimality criteria in a multidimensional space.…”

“…Let a regionally isolated electrotechnical complex (RIETC) be a set of isolated power supply systems (IPSS) united by some complex-inherent features [11]. The main specific features of RIETC, partially described in [12] and supplemented in this work, include the following:…”

“…− each IPSS of the considered aggregate is an electrotechnical generation and consumption complex (ETGC), which at the same time converts external energies of various types (chemical, thermal, solar, hydraulic, ..., hereinafter referred to as "external energy influence" (EEI)) into electrical energy consumed by a separate IPSSs; − all IPSSs included in the analyzed RIETC interact with each other only through "mutual weak relations and weak interactions" [11], hereinafter referred to as "external non-energy influences" (ENI); − all IPSSs included in the RIETC operate on the basis of some integral ultimate goal, conditioned by the requirements of a suprasystem or supersystem that subordinates RIETC [12] and interacts with RIETC through energy and non-energy connections; − non-energy influences inherent in the analyzed RIETC, affect the quality of functioning of the entire RIETC (including energy parameters) in the operating range of external influences.…”
