Wide-area protection and control (WAPAC) is a new technology in the smart grid system. The high penetration of wind farms in power systems is likely to have an adverse impact on the relay operation even if the short-circuit current in such systems decays rapidly due to crowbar resistance. By including various renewable sources, and information and communication technology components, the power grid will become more complex. Approaches based on wide-area monitoring system (WAMS) are developed to solve the current challenges of the future of high renewable resources penetration. This study provides the latest main components of the WAMS architecture and the innovation in WAPAC research development using phasor measurement units (PMUs). As the extensive article review in this area is given that show no solution until now for widearea protection in case of high wind farm penetration. A new wide-area protection based on PMUs is deployed. The main concept is based on describing by differential equations the dynamic operation of the transmission lines. In case of faults, the equations become non-linear and become difficult to be solved. This is the first time to develop such an idea to identify the protected faulted zone and guarantees sustainability for the power flow.

“…In current research, based on the extended traditional main protection algorithm, the principle of directional comparison pilot protection and differential current protection is introduced in wide-area backup protection. Differential current protection is characterized by not only needing accurate synchronization and having difficulty in solving influence on differential current of capacitive current and cumulative error in wide-area measurement [8,9]. Although directional protection requires less precise synchronization, its sensitivity is inadequate under complex conditions like high impedance grounding, system oscillation, power converse and two phases operation [10,11].…”

Based on the wide application of wide-area measurement system and synchronous digital hierarchy, wide-area relaying protection is becoming hot topic which can help to solve the problems about the complicated setting and coordination of traditional backup protection and cascading overload trip caused by power flow transferring. Based on sectional and centralizeddistributed wide-area relaying protection system architecture, a novel wide-area backup relaying protection algorithm is proposed in this paper. Combined with the distribution characteristics of line's sequence voltage and current when power system fault occurs, the algorithm can monitor the starting signal of each bus' sequence voltage, then select out a suspected faulty line by collating of bus's enable sequence voltage. At the same time, the criterion of identifying fault is formed with the proportion of sequence current phase and current amplitude in both ends of suspected fault line. When fault occurs in the range of the line, current's phase and amplitude are equal in both ends of the line. When fault occurs outside the range of the line, current's phase and amplitude are opposite in both ends of the line. The algorithm can decrease system's communication quantity and calculating quantity by only uploading the information of suspected faulty line. Meanwhile, the algorithm can eliminate the effects of line's distributed capacitance by using line model with distributed parameters. The algorithm could be set conveniently and could be used in the complexity operating condition such as grounding with high impedance, operating with two phases, translating fault and power transferring. Based on IEEE 10-machine and 39-bus system, Simulation results prove the effectiveness and adaptability of the method.

In this paper, a multiagent-based voltage and reactive power control in the case of a multiple contingency is presented. Incorporating the agent-based autonomous feature to the intelligence of the remote terminal units, the present power system control structure can be used to help in preventing system voltage collapse during catastrophic disturbances. The control algorithm is based on a decentralized architecture of intelligent agents and the determination of a local zone that can carry out quick countermeasures in a decentralized manner as a multiagent system (MAS) during an emergency situation. An adaptive determination of the local zones undergoing voltage collapse has been developed based on the electrical distances among the generators and loads. Once assigned, the elements of the Jacobian matrix can be used to determine the optimum actions that need to be carried out at each power system element (such as increasing the voltages of generators and load shedding) within the assigned local zone. The contract net protocol is used for agent interactions. Simulation results using the IEEE-57 bus system show that the proposed method can act quickly to respond to emergency conditions to ensure that voltage collapse can be avoided.
