“…Searching for technical, environmental and economic efficiency, micronetworks and virtual power plants are presented as identical concepts [9], [10]. However, in [11] [1], [11], [12], [13]. It is noteworthy to mention that the first definitions of VPP (2008) considered it as an integration mechanism equivalent to a micro-network.…”

In this paper, voltage stability in a distribution network is studied by integrating distributed energy resources (DER) as distributed generation and compensating elements, into a Virtual Power Plant for a distribution level (DVPP). Integration into a DVPP arises from the need to counter the various problems that DERS represents, due to different factors such as its dependence on climatic conditions, which are difficult to predict. A distribution network with industrial loads and distributed generation is considered, being fed by a power system IEEE-9 nodes

“…La versatilidad de las VPP permite que integren además de usuarios poseedores de DER elementos de la red como Plantas de procesamiento de residuos permitiendo establecer clúster económicos y energéticos en el marco de proyectos económica, social y medioambientalmente sostenibles Schäfer et al, 2015;Sowa et al, 2014) Las VPP facilitan la integración de los DER, permitiendo subsanar en gran medida inconvenientes ligados a la incertidumbre en el comportamiento de los elementos DER como la GD, gracias al manejo paralelo de tecnologías asociadas a sistemas de almacenamiento, y mecanismos de RD. La facilidad de adaptación de las VPP permite que participen en mercados de tipo DAM (Day Ahead Market: Mercado de día anterior) y en mercados de tipo BM (Balancing real time market: mercado de balance en tiempo real; Dietrich et al, 2015).…”

ResumenEn el presente artículo se propone un modelo de gestión para redes de distribución eléctrica que incluyan elementos de Generación Distribuida (GD), mediante el monitoreo constante a través de Unidades de Medida Fasorial (PMU). Se analizan los conceptos de PMU, GD, algunos modelos de gestión para redes y el lenguaje de modelado Unificado UML, que es usado como base para el proceso de modelado del sistema de gestión propuesto. Posteriormente, se ilustran las etapas de modelado, los elementos estructurales y la funcionalidad que tiene el modelo de sistema de gestión propuesto. Se concluye que por tratarse de modelos de diseños abiertos y genéricos, se permite fácilmente incluir nuevos parámetros o un nuevo direccionamiento de los elementos de red, o nuevas estrategias de control para cumplir la tarea de gestión que se requiera. Palabras clave: modelo de gestión; red de distribución eléctrica; generación distribuida; unidad fasorial de medición; UML Proposal of a management model for electrical networks with distributed generation using Phasor Measurement Units AbstractIn this article, a management model for electricity distribution networks is proposed. The electricity distribution network includes elements of distributed generation (DG). The network monitoring is done through Phasor measurement units (PMU). The concepts of PMU, DG, management models for networks and Unified modeling language UML are analyzed. The UML language is used as the basis for modeling process management system proposed. Later, stages of modeling, structural elements and functionalities of the proposed model management system are illustrated. It is concluded that being model of open and generic design it can be easily include new parameters, or change de direction of the network elements, 0r new control strategies that may be needed to fulfill a desired management task.

Abstract:In China, in order to integrate more renewable energy into the power grid, coal power flexibility retrofitting is imperative. This paper elaborates a generic method for estimating the flexibility potential from the rapid ramp rate and peak shaving operation using nonlinear programming, and defines three flexibility elastic coefficients to quantify the retrofitted targets. The optimized range of the retrofitted targets determined by the flexibility elastic coefficients have a reference significance on coal power flexibility retrofitting. Then, in order to enable economic decisions for coal power flexibility retrofitting, we address a profit maximizing issue regarding optimization decisions for coal power flexibility retrofitting under an assumption of perfect competition, further analyzing the characteristic roots of marginal cost equal to marginal revenue. The rationality of current compensation standards for peak shaving in China can also be judged in the analysis. The case study results show that economic decision-making depends on the compensation standard and the peak shaving depth and time. At a certain peak shaving depth and time, with rational compensation standard power plants are willing to carry out coal power flexibility retrofitting. The current compensation standard in Northeast China is high enough to carry out coal power flexibility retrofitting. These research conclusions have theoretical significance for China's peak shaving compensation standards formulation.
