“…The simulation results are all shown in Figure 5: First, to meet the requirement for plug in operation, the proposed information processing method updates its corresponding updating matrix to adapt the plug in operation according to Equation (4), only the new agent 6 and its neighboring agent 5 need to update during the plug in operation. Meanwhile, the number n changes to (n + 1) accordingly and is discovered by each agent based on Equation (8). In this case, assuming that τ 1 = 0.5, τ 2 = 1.0, β = 0.01.…”

“…Various kinds of load shedding schemes have been proposed during the past years, which can be classified into two types, namely centralized load shedding scheme and distributed load shedding scheme, respectively [6]. In [7][8][9], a centralized method was proposed to determine the most appropriate loads to be shed during under-frequency and under-voltage conditions. Although the centralized control scheme may seem like an appropriate solution in coordinating generators and loads, however, it is costly and suffers from failures due to requiring a central controller.…”

This paper addresses a multiagent-based distributed load shedding scheme to restore frequency for the microgrids during islanded operation. The objective of the proposed scheme is to realize a distributed load shedding considering its associated cost and the capacity of the flexible loads. There are two advantages of the proposed scheme: (1) it is a distributed scheme using average-consensus theorem, which can discover the global information when only communications between immediate neighboring agents are used, moreover it can meet the requirements of plug-and-play operations more easily than a centralized scheme; (2) it is a new adaptive load shedding through the comprehensive weights which take into accounts the cost of load shedding and the capacity of flexible loads, these comprehensive weights are evaluated locally by making use of the adaptability and intelligence characteristics of agents. Simulation results in power systems computer aided design (PSCAD) illustrate the validity and adaptability of the proposed load shedding scheme.

“…There has been more recent work on adaptive and combinational load shedding by a lot of researchers. Different methods for adaptive load shedding are adopted in [23], [24], [25], [26], [27], [28]. The authors of [18] talk about interruptible and uninterruptible parts of every load and suggest shedding the interruptible part of every load in the system as a mitigation strategy.…”

“…The concept of fairness in the sense of economics has been briefly introduced in [6] where fairness criteria namely "free from envy", "efficiency", "accountability" and "altruism" have been checked for a centralized optimization method of multi-TSO power system. Successful centralized coordination has been reported only for rather small-scale power systems [7][8][9]. …”

This two-part paper deals with the coordination of the control actions in a network of many interacting components, where each component is controlled by independent control agents. As a case study we consider voltage control in large electric power systems, where ever-increasing pressures from the liberalization and globalization of the electricity market has led to partitioning the power system into multiple areas each operated by an independent Transmission System Operator (TSO). Coordination of local control actions taken by those TSOs is a very challenging problem as poorly coordinated operation of TSOs may endanger the power system security by increasing the risk of blackouts. This coordination problem involves many other issues such as communication, abstraction and last but not least optimization. This first part of the paper is devoted to the principals of the coordination control, addressing some of those issues using as a case study the problem of coordination control for avoiding voltage collapse in large-scale multi-area power systems.
