Resource Decision

In order to build a truly open OpenDSS and enhance the complexity of decision-making DSS for solving the problem of voltage control. a new model was given based on MAS in grid environment. Making use of the intelligence of MAS and adaptive capacity, based on the reasoning mechanisms for task decomposition and resource decision-making grid matching, a new intelligent algorithm based on MAS in order to improve its control effect, and the paper uses the kind of algorithm to coordinated secondary voltage control. The simulation results show the voltage control based on the algorithm have better global best properties and coordinate voltage effectively than routine method.

Perturbation Effect

In the spacecraft formation task, a spacecraft failure or formation of the mission to change the need for reconstruction of the formation. In the process of reconstruction, how to carry out spacecraft anti-collision has been widespread concern. In this paper, barrier theory is adopted. By establishing Hamilton function, the optimal control law is obtained. According to the theory of barrier construction, the corresponding barrier trajectory is constructed. Then, the barrier is divided into collision area and non-collision area, so as to realize the formation flight anti-collision design. The simulation results show that the method can avoid the perturbation effect and has a certain theoretical value for the anti-collision between the spacecrafts during the formation process.

Event Triggered

This paper presents a secondary voltage control scheme with a distributed event-triggered mechanism for multiple distributed generators in droop-controlled microgrids. First, considering the issue of limited bandwidth of a communication network in a practical application, two types of distributed event-triggered mechanisms are proposed to reduce the information transmission pressure, while preserving the desired control performance. Then, based on the proposed triggering schemes, distributed secondary controllers are designed for distributed generators. Finally, simulation results demonstrate that by using the control strategy, the voltages of distributed generators are synchronised to their nominal values.
