“…The inverse of the load restoring property of the LTC is used to control the power consumption in a certain area with an LTC: the power consumption of voltage sensitive loads can be reduced by lowering the secondary voltage. The method, first introduced in our previous work [42], is to adjust the voltage set-point of the LTC to achieve a certain amount of virtual load shedding. The advantage of this method, compared to the existing voltage set-point reduction methods (e.g.…”

“…Note that this method requires a detailed knowledge about the load behavior. Because an error in the load model results in an inaccuracy in the amount of load being shed, in [42], a sensitivity analysis is performed, and it can be concluded that an error in the load model is of minor importance. In addition, the closed loop of the coordinated HABVIP controller cancels out individual errors of the actuators.…”

SUMMARY In this paper, a new method for online voltage instability control suitable for smart grid application is proposed. The method uses the Maximum Loadability Index to determine the amount of load relief necessary to restore stability. This measure can be determined based on local measurements. The load relief is obtained by: increase of local generation, virtual load shedding via adjusting the Load Tap Changers (LTCs) set‐point, intelligent load control and the increase of reactive power compensation from Static Var Compensators. For the local generation, the control of two types is described: for micro Combined Heat and Power (micro‐CHP) units and for large synchronous generators. In order to obtain constant power supply from a group of micro‐CHPs, a Virtual Power Plant coordination method is proposed. The control of the actuators is outlined, and a method is described to coordinate their actions. Based on simulations it is demonstrated that the proposed method works properly: voltage collapse can be avoided, and voltage stability is restored. A sensitivity analysis is performed to determine the optimal settings of the coordinated controller. Furthermore, the merit of including reactive power control in the proposed control strategy is investigated. Compared to classical controls, such as Under‐Voltage Load Shedding and LTCs tap blocking, the method performs better. Copyright © 2013 John Wiley & Sons, Ltd.

In [11], the detailed control of the load tap changer(LTC) is given. A control system based on multi-agent technique that coordinates different discrete and continuous control devices during the post-disturbance period to prevent voltage collapse of the whole system is presented in [12].…”

The presence of distributed generators (DGs) with high penetration poses new challenges in the management and operation of electrical grids. Due to the local character of DGs, they could in principle be used in emergency situations to prevent a voltage instability event of the grid. In this paper, a certain method is proposed to coordinate the operation of virtual power plant (VPP) and conventional voltage regulation device to improve the static voltage stability of distribution network with the multi-agent framework. The concept and the general framework of this coordinated control system is introduced, and the voltage instable nodes are determined based on the voltage instability indicator. The voltage coordinated control model of the distribution system is established according to the multi-agent consistency control theory and the coordinated controllers for agents are designed by solving a problem with bilinear matrix inequality constraints. The suggested method is implemented on an IEEE 33 nodes test system and the simulation results show its efficiency and validity.
