“…Another conventional reliability allocation method focuses on multiobjective optimization [4], including cost minimization [7] and redundancy allocation [8]. In addition, some smart methods like event-triggered-based [9] and Newton-Raphson-based [10] distributed algorithm and small-signal model [11] are proposed to improve multienergy systems' reliability [9,10,12] and increase converters' stability. Nevertheless, the aforementioned methods still cannot satisfy the reliability allocation demands of the early design phase for the modern complex system of turrets.…”

Existing methods cannot satisfy the reliability allocation demands of the early design phase for the modern complex system of NC turrets. Motivated by the need of practical application, this paper proposes a new and practical reliability allocation method in the early design stage for NC turrets considering failure mode and system complexity, information inaccessibility, and expert knowledge limitation. First, the fault tree of a NC turret is quickly built to clear the relationship between the system's compositions and failure modes up. Second, the happening probability of each failure event in the fault tree is firstly calculated by fuzzy expert evaluation to provide the reliability allocation with complete information. ird, by discussing the practical meaning of every layer in the fault tree, the proposed allocation strategy is within the experts' knowledge scope for evaluating accurately. Eventually, the application result of the AK36100 A turret is presented and compared with some existing allocation methods, illustrating the rationality of the proposed allocation method.

“…Since the proposed algorithm also requires the initial power allocation starts from a predetermined value, the algorithm may require the re-initialization when the operation condition is changed. Furthermore, the authors in [25] 1 propose an event-triggered based energy management system for multi-energy systems to maximize their day-ahead social welfare and smooth out the real-time loads variations. However, the algorithm requires each agent to exchange two auxiliary variables between neighbours, which might result in additional communication cost.…”

In this paper, to reduce required capacities for information exchanges in microgrids, a novel distributed eventbased algorithm is proposed for optimal energy management in a microgrid. Aiming at optimally scheduling the energy supplier's generation, an objective function is formulated to minimize the total cost of maintaining the supply-demand balance with considering power losses. Regarding each participant as an agent, the proposed algorithm is implemented in a distributed manner based on a multi-agent system framework. Therefore, each agent only exchanges information with its neighbours through a local network. Additionally, comparing with the periodical communication of sampled-data mechanisms, the adopted event-based scheme achieves satisfactory performance by using significantly less communication between participants. As a result, it further facilitates the development of networked microgrids. Furthermore, concerning the privacy of participants, the proposed algorithm is implemented without exposing owners' private preferences. The effectiveness of the proposed distributed algorithm is validated through several simulation studies.

“…Meanwhile, the accuracy of the power flow calculation without considering virtual impedance would be reduced. Furthermore, the economic dispatch and stability recovery for the Energy Internet with multi‐DRGs consisting of numerous distributed renewable source need quick power flow calculation . Thus, this paper proposes a decoupled power flow calculation to improve the convergence speed in accordance with the circuit characteristics of microgrid with multi‐DRGs based on the droop control strategy with adaptive virtual impedance.…”

Summary This paper analyzes the equivalent impedance characteristics of the ac microgrid with distributed renewable energy generations (DRGs) based on the droop control and proposes a decoupled power flow calculation method. The droop control strategy with adaptive virtual impedance has become an effective solution to utilize the DRG. To analyze the characteristics of the DRG, a microgrid consisting of multi‐DRGs based on distributed consensus‐based secondary voltage droop control with adaptive virtual impedance is researched. Considering the characteristics of the DRGs, a decoupled power flow calculation can be proposed to satisfy the quick power flow calculation in order to achieve economic dispatch and stability recovery for the microgrid. Furthermore, the accuracy of the power flow calculation with considering virtual impedance is improved. Moreover, a small microgrid, including three DRGs, has been modeled and simulated using the MATLAB/Simulink. Eventually, the decoupled power flow calculation is tested on three test case systems.
