Розглянута з одного боку змінна систе-ма електропостачання, а з другого -неста-більна система електроспоживання. В рів-новагу системи можуть привести лише процеси, що в них протікають під дією взає-мозв'язаних зовнішніх і внутрішніх чинників. Використані мережі Петрі та теорія графів. Встановлено, що на початку формуються основні чинники, які визначають ефектив-ність електропостачальних систем, далі за допомогою орграфу будується модель проце-сів та виконується оптимізація. Отримані результати оптимізації важливі при проек-туванні та експлуатації електроенергетич-них мереж, сприяють зменшенню енергетич-них втрат Ключові слова: електроенергетичні мере-жі, електропостачальні системи, ефек-тивність, електроспоживання, електропо-стачання, чинники енергетичного процесу, моделювання, орграф Рассмотрена с одной стороны перемен-ная система электроснабжения, а с другой -нестабильная система электроснабжения. В равновесие системы могут привести лишь процессы, в них протекающие под действием взаимосвязанных внешних и внутренних фак-торов. Использованы сети Петри и теория графов.

“…It is technically possible to have both grid-integrated and grid-defected operation at household level and the economic and environmental assessment and evaluation of the former system is promising [19,[27][28][29]. Despite falling prices of DERs, the grid-defected system for individual households, on the other hand, is not yet economically attractive.…”

“…On the other hand, the grid-defected system has to meet all the demand locally. The rising regulated cost in the energy bills and decreasing DERs cost, are creating an enabling environment for customers to get disconnected from the grid and manage their own local grid [19,[27][28][29][30].…”

Local Alternative for Energy Supply: Performance Assessment of Integrated Community Energy Systems

et al. 2016

Integrated community energy systems (ICESs) are emerging as a modern development to re-organize local energy systems allowing simultaneous integration of distributed energy resources (DERs) and engagement of local communities. Although local energy initiatives, such as ICESs are rapidly emerging due to community objectives, such as cost and emission reductions as well as resiliency, assessment and evaluation are still lacking on the value that these systems can provide both to the local communities as well as to the whole energy system. In this paper, we present a model-based framework to assess the value of ICESs for the local communities. The distributed energy resources-consumer adoption model (DER-CAM) based ICES model is used to assess the value of an ICES in the Netherlands. For the considered community size and local conditions, grid-connected ICESs are already beneficial to the alternative of solely being supplied from the grid both in terms of total energy costs and CO 2 emissions, whereas grid-defected systems, although performing very well in terms of CO 2 emission reduction, are still rather expensive.

“…Such locations may even want to achieve energy 'independence'. However, this may become true in any context relying on per (energy) unit use-of-system (UoS) charges to recoup grid costs, as reducing utilization of grid electricity increases the per unit charge required to recover the largely fixed grid costs [2].…”

Abstract-This paper presents a flexible, multi-energy district/community optimization model which can consider multiple energy service demands (hot water, base electricity, space heating/cooling), thermal and electrical energy storage, and solar photo-voltaic generation. The formulation can model various levels of virtual and physical aggregation and accommodate various different pricing structures (on energy and capacity). The model is used to demonstrate how thermal and electrical storage can alleviate network constraints, and how various commercial arrangements for relieving these constraints are effective under different aggregation options. Peak demand, annual cash flow (by component) and measures of energy independence are presented as assessment metrics.
