Event-Based Distributed Secondary Control for AC Islanded Microgrid With Semi-Markov Switched Topology Under Cyber-Attacks
نویسندگان
چکیده
The operation of a microgrid (MG) is easily affected by the environment, which leads to change communication topology among distributed generations (DGs). Most existing results on secondary control MG consider that connection fixed, or just simply switched arbitrary form. In this article, more general semi-Markov process introduced describe such switching, i.e., switching regarded as random system mode under probability distribution. Then, out comprehensive consideration inevitable network constraints, article proposes resilient method for AC islanded MG. our strategy, security, burden, and transmission delay are all considered in controller design. An event detection mechanism used protocol information interaction DGs, reducing burden effectively. And cyber-attack model follow Bernoulli distribution, neighbors' each DG may be attacked with possible probability. Based feedback linearization, studied problem cast into tracking synchronization first-order multiagent systems. Lyapunov functional prove proposed strategy theoretically, its effectiveness verified modified IEEE 34 bus test system. result shows can reduce numbers over 80% premise realizing frequency restoration accurate real power sharing MG, rate also reduced about 40% compared method.

Agent based distributed control of islanded microgrid - Real-time cyber-physical implementation
In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, ...
متن کاملSecondary Control for Voltage Unbalance Compensation in an Islanded Microgrid
In this paper, the concept of secondary control is applied for voltage unbalance compensation in an islanded microgrid. The aim of the proposed control approach is to enhance the voltage quality at the point of common coupling (PCC). Unbalance compensation is achieved by proper control of distributed generators (DGs). The DGs control structure mainly consists of active and reactive power contro...
متن کاملSoftware-Defined Microgrid Control for Resilience Against Cyber Attacks
Microgrids (MGs) rely on networked control supported by off-the-shelf wireless communications. This makes them vulnerable to cyber-attacks, such as denial-of-service (DoS). In this paper, we mitigate those attacks by applying the concepts of (i) separation of data plane from network control plane, inspired by the software defined networking (SDN) paradigm, and (ii) agile reconfiguration of the ...
متن کاملA Distributed Control Architecture for Autonomous Operation of a Hybrid AC/DC Microgrid System
Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...
