“…Currently, there is a significant number of research and applications of risk assessment technology in the field of wind power [8][9][10][11][12], but relatively few research on the risk assessment technology of electrical fire in high-rise buildings, and the few assessment methods are still qualitative analysis based on traditional expert experience. In Reference [13], the fault tree model, analytic hierarchy process and grey relation analysis were adopted to conduct qualitative and quantitative analysis of the causes of high-rise building fire, but the influence of indexes on each other was ignored, and the evaluation methods were relatively single.…”

This paper investigates the risk assessment method of electrical fires of high-rise buildings based on hybrid decision models considering asymmetric proximity. Based on the occurrence mechanism of electrical fires in high-rise buildings, a four-level evaluation index system considering the disaster causing body, fire site environment, affected body, and fire driving factors is established based on FP growth mining association rules, and the risk grade is divided further. An improved DEMATEL+ANP index weight assignment method for balancing the interaction relationship between indexes is proposed, and a hybrid decision model for electrical fire risk assessment in high-rise buildings, taking further account of asymmetric proximity and improved evidence cloud theory. Combined with specific examples, the effectiveness of the proposed building electrical fire risk assessment method is verified. This method can better balance each risk evaluation index, fully considering the fuzziness and randomness in the electrical fire risk assessment of high-rise buildings, and improve the accuracy and applicability of electrical fire risk assessment.

“…Some authors have studied this question. For example, without giving much detail, Faghihi et al state that both wind productions and loads are correlated with themselves but not with each other. The combined heat and power (CHP) is independent from another CHP and from wind and loads.…”

Summary The development of renewable generation connected to the distribution network can create overvoltage or overcurrent situations leading to expensive upgrades of the network. Solutions such as production curtailment could avoid these expenditures, but in order to take full advantage of these new solutions, one must first appropriately model the statistical behaviour of loads and generation over several years with a high level of uncertainties. This paper performs a statistical analysis on 4254 real‐world generation time series that run over about 2 years, with a 10‐minute time step, for four different types of generation technologies. This large dataset was made available thanks to a partnership with the major French distribution system operator (DSO), Enedis. The objective is to develop probabilistic models of the power output for each type of generator and also of the statistical dependency between two generators and between generation and load and to apply them on an interconnection case study.

“…Una forma sería buscar los mecanismos de compensación de saldos, para fomentar la generación distribuida, y otra sería utilizar al sistema eléctrico principal como un sistema equivalente de almacenamiento que genera derechos de consumo. El consumidor pagaría el coste por el servicio de almacenamiento, abonando unos peajes por el uso de la red y la gestión de los excedentes de energía (Faghihi et al 2015).…”

Urban energy systems are an essential part of cities, which require a reliable and abundant supply of electricity and other services (such as water, fuel for transportation or food). On the other hand, the double crisis related to the use of fossil fuels, the availability crisis and the pollution crisis, require the prompt implementation of a renewable energy transition. The analysis of urban electrical uses and their relation with the resources of the territory, the economy and the environment yields very valuable information to plan the renewable energy transition in urban environments. The present work contributes to the field of energy transitions with a methodology based on two concepts: Energy Hub (EH) and Virtual Power Plant (VPP). This methodological contribution allows us to analyse the renewable energy flows (intermittent and random) from the top and bottom approaches (Top Down & Bottom Up), in order to diagnose an urban energy system in an integral way. A simple and inexpensive tool was developed in order to help public utilities perform an efficient data collection and treatment in order to diagnose and manage renewable urban energy system in a geo-referenced environment according to the proposed methodology. This methodology is applied to Loja, a city of about 200,000 inhabitants located in southern Ecuador, to obtain the relation between its electricity use and the generation from the neighbouring Villonaco Wind Power Plant, the first wind farm in continental Ecuador with a power rating of 16.5 MW. The city is electrically relatively isolated, at the end of a branch of the National Interconnected System (SNI), which entails a certain vulnerability. The integration of the wind farm reduces this vulnerability, as it provides an energy autonomy that ranges from 40% to 60% on a yearly average, and cuts down greenhouse gas emissions by 25,000 MgCO2/year from the previous 62,000 MgCO2/year. The electric flows of Loja are analysed for a period of one year using measured data. The results of this analysis lead to a proposal to optimise the electricity network using the infrastructure of the National Interconnected System as an equivalent storage system to manage the generation surpluses. Additionally, the tool is used to study the effect of two expansion scenarios of the Wind Power Plant (28 MW and 33 MW) on the energy grid and autonomy of Loja. Demand response strategies for the industrial sector are also considered in order to reduce peak load and the need for storage or energy imports. This strategy could be extended to commercial and residential users. Finally, several future research lines are proposed: Integration of urban decentralized generation and storage systems; Experimentation with tools of monitoring and control in real time; Proactive management of energy resources for distribution networks with Virtual Generation Plants; Identification of barriers and engines for the diffusion of new renewable energy services. Los sistemas energéticos urbanos son una parte esencial de las ciudades. Estas para funcionar requieren un suministro fiable y abundante de electricidad, así como de otros servicios como son el agua, el combustible para el transporte, o los alimentos. Por otro lado, la doble crisis de recursos energéticos fósiles, de disponibilidad y de contaminación, obliga a avanzar en la transición energética renovable. El análisis pormenorizado de los usos eléctricos sus vínculos con los recursos del territorio, la economía y el medio ambiente ofrece una información muy valiosa para proyectar la transición energética en entornos urbanos. El presente trabajo pretende contribuir al campo de las transiciones energéticas en base a una metodología que combina dos conceptos: el Multiportador de Energía (Energy Hub - EH) y las Plantas de Generación Virtual (Virtual Power Plant - VPP). Este aporte metodológico permite analizar los flujos de energía renovables (intermitentes y aleatorios) desde los enfoques ascendente y descendente (Top Down & Bottom Up), con el fin de diagnosticar un sistema energético urbano de forma integral. Se presenta una herramienta sencilla y económica que permite a las empresas de servicios públicos adquirir y realizar un tratamiento eficaz de los datos, con el fin de diagnosticar y gestionar el sistema energético urbano renovable en un entorno georreferenciado siguiendo la metodología propuesta. La metodología se aplica a Loja, una ciudad de unos 200 000 habitantes ubicada al sur de Ecuador, para obtener la relación entre los usos eléctricos y la generación de la Central Eólica Villonaco, la primera planta eólica de Ecuador continental, y que tiene una potencia nominal de 16,5 MW. La ciudad se encuentra relativamente aislada eléctricamente, al final de una rama del Sistema Nacional Interconectado (SNI), lo que conlleva una cierta vulnerabilidad. La integración de la planta eólica reduce esta vulnerabilidad, puesto que proporciona una autonomía energética a la zona urbana que oscila entre el 40 y 60% anual, y reduce las emisiones de gases de efecto invernadero en unos 25 000 MgCO2/año, sobre los 62 000 MgCO2/año iniciales. Se analizan los flujos eléctricos reales (obtenidos a partir de mediciones) en un periodo de un año, y se propone la optimización de la red utilizando la infraestructura del Sistema Nacional Interconectado como un sistema equivalente de almacenamiento para gestionar los excedentes de generación. Adicionalmente, se utiliza la herramienta para estudiar dos escenarios de expansión de la Central Eólica (de 28 MW y 33 MW) y el efecto que podrían tener en la red eléctrica y la autonomía de la ciudad. También se considera una estrategia de gestión de respuesta a la demanda del sector industrial para reducir la carga de pico y con ello la necesidad de almacenaje o importación de energía. Esta estrategia podría extenderse a los consumos residenciales y comerciales. Finalmente, se proponen varias líneas de investigación futuras: Integración de la generación descentralizada urbana y sistemas de almacenamiento; Experimentación con herramientas de monitorización y control en tiempo real; Gestión proactiva de recursos energéticos para redes de distribución con Plantas de Generación Virtual; Identificación de las barreras y los motores de la difusión de nuevos servicios energéticos renovables.
