“…The GOOSE defined in IEC61850 is one of the important message types for protection and control in the power substation [18]. It has the characteristics of high reliability and fast response, and is widely considered as the best protocol for LCDP in distribution networks [6,12,14,19,20]. However, the transmission mechanism of GOOSE is configured based on a MAC address, the work area of it is limited to local area network (LAN).…”

“…In addition to the PD, other devices in the distribution network also use this communication system, such as micro-environment monitor and supervisory control and data acquisition (SCADA) devices. In addition, with the development of the digitally enabled substation [21], feeder-based microgrid [19], and other technologies, more devices such as the intelligent transformer terminal unit (TTU), micro-phasor measurement unit (µPMU) and DG controller will be connected to the feeder, and the number of these devices will be far greater than 256. The existing GOOSE protocol cannot meet the requirement.…”

As one of the core technologies of distributed feeder automation (DFA), line current differential protection (LCDP) can locate faults quickly and accurately and have the ability to cope with multi-directional flow. However, LCDP algorithm has high requirements for communication speed, and is sensitive to communication quality. In order to apply the LCDP algorithm to a real project, the communication system and its impacts on LCDP need to be studied in depth. In this paper, the design method of a communication system for LCDP, including communication mode, topology, communication protocol, and synchronization, is analyzed in detail. For better parameter determination, the communication models are investigated, and the impact of time delay, data loss, and jitter on LCDP are discussed. Further, the distribution network based on a real project is built in a cyber-physical co-simulation environment, and the impact of electrical fails and communication fails on LCDP are studied. The results show that the design method and parameters determination method proposed in this paper are effective.

“…Microgrids are a subset of smart grids that achieve grid deployment in small regions. A microgrid acts as a single controlled entity that is formed by a group of interconnected load and demand resources with communication and control capabilities [3]. It has a well-defined electricity boundary with a limited number of connection points to the utility grid such that it can operate in either gridconnected or islanded mode.…”

Distribution feeder microgrid (DFM) built based on existing distributed feeder (DF), is a promising solution for modern microgrid. DFM contains a large number of heterogeneous devices that generate heavy network traffice and require a low data delivery latency. The information-centric networking (ICN) paradigm has shown a great potential to address the communication requirements of smart grid. However, the integration of advanced information and communication technologies with DFM make it vulnerable to cyber attacks. Adequate authentication of grid devices is essential for preventing unauthorized accesses to the grid network and defending against cyber attacks. In this paper, we propose a new lightweight anonymous device authentication scheme for DFM supported by named data networking (NDN), a representative implementation of ICN. We perform a security analysis to show that the proposed scheme can provide security features such as mutual authentication, session key agreement, defending against various cyber attacks, anonymity, and resilience against device capture attack. The security of the proposed scheme is also formally verified using the popular AVISPA (Automated Validation of Internet Security Protocols and Applications) tool. The computational and communication costs of the proposed scheme are evaluated. Our results demonstrate that the proposed scheme achieves significantly lower computational, communication and energy costs than other state-of-the-art schemes.

“…The integration of these renewable DG systems refreshes the electric distribution networks and provides new opportunities and benefits. Its integration, however, brings new challenges for the protection, control, and operation Energies 2018, 11, 2167 2 of 22 of these electric networks [3]. For example, traditional electric distribution networks were designed, controlled, and operated as passive systems, whereas the integration of DG transforms them into active power networks where the energy flow is now bidirectional.…”

“…A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island mode [6]." Currently, many other organizations and research groups define microgrids with very similar definitions, including the concept of a system having Points of Common Coupling (PCC), of multiple controllable loads and distributed generation, energy storage, of islanding from the grid, and, recently included, the concept of a power system cell [3]. A microgrid must accomplish certain special needs, such as improving local security, reducing loss connection, supporting local tensions, correcting the voltage drop, or providing uninterruptible power supplies, etc.…”

Optimal Energy Management within a Microgrid: A Comparative Study

et al. 2018

View full text Add to dashboard Cite

In this work, we focus on optimal energy management within the context of the tertiary control of a microgrid operating in grid-connected mode. Specifically, the optimal energy management problem is solved in a unified way by using the optimal power flow (OPF) and day-ahead concepts. The elements considered in the microgrid are a photovoltaic panel, a wind turbine, electric vehicles, a storage system, and a point of common coupling with the main grid. The aim of this paper consists of optimizing the economic energy dispatch within the microgrid considering known predictions of electricity demand, solar radiation, and wind speed for a given period of time. The OPF is solved using three different algorithms provided by the optimization toolbox of MATLAB® (R2015a, MathWorks®, Natick, MA, USA): the interior point method (IP), a hybrid genetic algorithm with interior point (GA-IP), and a hybrid direct search with interior point (patternsearch-IP). The efficiency and effectiveness of the algorithms to optimize the energy dispatch within the microgrid are verified and analyzed through a case study, where real climatological data of solar irradiance, wind speed in Almería city, photovoltaic system data, and room load from a bioclimatic building were considered.
