Abstract

In this work, an agent-based scheme is proposed for distributed underfrequency load shedding (UFLS). The key concept is a consensus weighting protocol (CWP) for agents to reach an agreement. Unlike the well adopted average-consensus protocol (ACP), the proposed CWP enables each agent to converge to its weighted portion of the sum of all initial values. Thus, the proposed CWP is more suitable for the UFLS application, as it allows load buses with a higher level of loading to shed more, rather than reducing by the same average value over all load buses as required by the ACP. Proof of convergence for the proposed CWP is derived and presented in this paper, together with the constraints. For implementation of the multi-agent system (MAS), the monitoring, estimation, and distribution steps are developed. Two study cases and the simulation results are provided to validate the performance of the proposed agent-based UFLS scheme.

Consensus Weighting of a Multi-Agent System for Load Shedding

Multi-agent systems and their applications

Journal Article Xie, Jing ; Liu, Chen-Ching - Journal of International Council on Electrical Engineering

The number of distributed energy components and devices continues to increase globally. As a result, distributed control schemes are desirable for managing and utilizing these devices, together with the large amount of data. In recent years, agent-based technology becomes a powerful tool for engineering applications. As a computational paradigm, multi agent systems (MASs) provide a good solution for distributed control. Here in this paper, MASs and applications are discussed. A state-of-the-art literature survey is conducted on the system architecture, consensus algorithm, and multi-agent platform, framework, and simulator. In addition, a distributed under-frequency load shedding (UFLS) scheme is proposed using themore »« less

An adaptive approach to load shedding and spinning reserve control during underfrequency conditions

Journal Article Chuvychin, V N ; Gurov, N S ; Venkata, S S ; ... - IEEE Transactions on Power Systems

Emergency conditions arising due to generating power deficiency and the consequent drop in power system frequency can lead to system collapse and a large scale loss of load. Underfrequency load shedding (UFLS) is a globally accepted practice to handle this situation. Most UFLS schemes use pre-specified step sizes based upon frequency measurements. This paper presents an adaptive scheme which uses both frequency and rate-of-change of frequency measurements to dynamically set UFLS relays if more than one generation outage is experienced. It then proposes a technique for coordinating UFLS and the activation of spinning reserves through localized governor control. Recent developmentsmore »« less

Load shedding on an isolated system

Journal Article Concordia, C ; Fink, L H ; Avramovic, B ; ... - IEEE Transactions on Power Systems

Underfrequency load shedding (UFLS), in previous generations shunned by the industry as an admission of poor planning and operation, has become a generally accepted practice. There is by now a considerable body of literature on the subject, dating back to midcentury. That literature, however, deals with the subject in the context of large interconnected systems. Smaller, isolated systems, which are more vulnerable to serious disturbances, have operating characteristics that require somewhat different guidelines, due to their lower inertia, limited reserves, and lack of access to off-system assistance. This paper reviews the objectives and principles of UFLS, and reports their application,more » to a small island power system.« less

Determination of load block compositions in load-shedding schemes

Journal Article Tsang, C P ; Wong, K P - IEEE Comput. Applicat. Power; (United States)

Large disturbances, such as short-circuit faults on a power system, lead power plants into a transient operating mode. Disturbances may propagate over a wide area in the system and may affect groups of generators, loads, and the interconnected network. In some extreme cases, a network may be separated into islands. In these islands, the load demand and the power generated may not be balanced. When there is a deficiency in power generation, frequency and voltage will drop. A typical validation of frequency with time is shown in Fig. 1. If underfrequency occurs in an island, loads are rejected in stagesmore »« less
