“…Returning to the representational needs for our work, an electrical (LV, MV or HV) substation with digital controls and communication capabilities is adequately expressed using the information models in the IEC 61850 group of standards [65]. The communication performance requirements for inter-substation relaying and SCADA telemetry are also well represented [66]. The generic object-oriented, building block for representing function elements, per the standard, is called a "logical node."…”

Renewable portfolio standards are targeting high levels of variable solar photovoltaics (PV) in electric distribution systems, which makes reliability more challenging to maintain for distribution system operators (DSOs). Distributed energy resources (DERs), including smart, connected appliances and PV inverters, represent responsive grid resources that can provide flexibility to support the DSO in actively managing their networks to facilitate reliability under extreme levels of solar PV. This flexibility can also be used to optimize system operations with respect to economic signals from wholesale energy and ancillary service markets. Here, we present a novel hierarchical scheme that actively controls behind-the-meter DERs to reliably manage each unbalanced distribution feeder and exploits the available flexibility to ensure reliable operation and economically optimizes the entire distribution network. Each layer of the scheme employs advanced optimization methods at different timescales to ensure that the system operates within both grid and device limits. The hierarchy is validated in a large-scale realistic simulation based on data from the industry. Simulation results show that coordination of flexibility improves both system reliability and economics, and enables greater penetration of solar PV. Discussion is also provided on the practical viability of the required communications and controls to implement the presented scheme within a large DSO.

“…Thus, Figure 7 serves the general purpose of providing the relation between the size of transferred data and latency for inter-substation communication. This fits the applications that require the exchange of data messages in order to transfer information between substations (e.g., tele-protection or phasor measurements) [ 36 ]. For instance, IEEE C37.118 [ 37 ] defines two performance classes.…”

“…These data packets can be transferred simultaneously from the seven substations within an end-to-end delay of 9.6 ms using the proposed HWN configuration. Recently, IEC 61850-90-1 has defined the communication requirements (in terms of message types and transfer times) between substations [ 36 , 38 ]. The obtained end-to-end delay (9.6 ms) meets the most stringent delay requirement for IEC 61850-90-1, which is assigned to message performance class (MPC) Type 1 and Type 4 (maximum 10 ms transfer time) [ 38 ] according to Table 4 .…”

Supporting a conventional power grid with advanced communication capabilities is a cornerstone to transferring it to a smart grid. A reliable communication infrastructure with a high throughput can lay the foundation towards the ultimate objective of a fully automated power grid with self-healing capabilities. In order to realize this objective, the communication infrastructure of a power distribution network needs to be extended to cover all substations including medium/low voltage ones. This shall enable information exchange among substations for a variety of system automation purposes with a low latency that suits time critical applications. This paper proposes the integration of two heterogeneous wireless technologies (such as WiFi and cellular 3G/4G) to provide reliable and fast communication among primary and secondary distribution substations. This integration allows the transmission of different data packets (not packet replicas) over two radio interfaces, making these interfaces act like a one data pipe. Thus, the paper investigates the applicability and effectiveness of employing heterogeneous wireless networks (HWNs) in achieving the desired reliability and timeliness requirements of future smart grids. We study the performance of HWNs in a realistic scenario under different data transfer loads and packet loss ratios. Our findings reveal that HWNs can be a viable data transfer option for smart grids.
