Abstract

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.

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.

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

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

Guam Power Authority automatic underfrequency load shedding study

Conference Wong, H.H. ; Flores, J.C. ; Fang, Y. ; ...

This paper describes the development of a new automatic underfrequency load shedding scheme on the Guam Power Authority`s (GPA) system using a transient stability simulation program. The new scheme strives to minimize the amount of load shed by selecting frequency settings based on the severity of generation or load unbalance and the availability of spinning reserves. The fast speed of frequency decay due to loss of generation is shown to be particularly pronounced in an island system, requiring more careful design of any load shedding scheme than large interconnected systems. The use of a well-prepared transient stability study model allowsmore »« less
