“…A controlled voltage source is used to model the microgrid and the load included in the microgrid is presumed to be resistive. The system data and parameters values are stated in [13]. The behavior of the developed series power flow controller is investigated in different operation modes (capacitive and inductive) for each type of the control methods.…”

“…An active power point of common coupling (PCC) control method has been introduced in [14] by installing a smart transformer at the interface point between the main network and the microgrid to control the active power exchange between both networks using voltage-based droop control concept. Two novel control strategies applied on a transformerless H-bridge inverter connecting the main grid and the microgrid have been implemented for power flow control between both of them, where their feasibility is verified during different operation modes [13]. A new control methodology has been evolved to run the H-bridge inverter as a power flow controller between the main network and the microgrid [22].…”

This paper investigates the performance of various power control structures on a series power flow controller comprised as transformerless H-bridge inverter under different operating conditions. This power flow controller connects the main grid with the microgrid as it is seriesly attached with the distribution line. Three different control strategies are implemented to regulate the power flow at the interface point using the series power flow controller. The feasibility of the regulation approaches is verified by varying the modulation index and the reference DC-link voltage during different operation modes. Also, the performance of the control strategies is verified under load divergence condition during two different operation modes. The results showed the efficacy of the developed regulation methods in injecting series voltage at point of common coupling (PCC) either during the capacitive or the inductive operation mode. Also, the obtained results reveal the stability and reliability of the regulation methods and the microgrid operation when either the reference DC-link voltage or the modulation index are increased.

“…The local one is based only on local measurements and only through a communication line can it be made available among the various microgrids in order to achieve coordinated control. From the method of communication, three strategies can be obtained: basic coordinates (or decentralized control), centralized and distributed [25,26]: decentralized control [27] can be considered an extension of local control and it is based only on local measurements, while centralized and distributed control strategies are based on digital communication technologies [28,29].…”

In modern aircraft, energy supply management has become a critical matter, since many aboard electrical loads have to be supplied, especially those related to flight safety. However, at the same time, the size and weight of electrical generators must be limited because of their on-board installation. In this paper, the Mixed Integrated Linear Programming (MILP) methodology has been used to formulate the Supervisor definition of the direct current (DC) microgrid (MG) on-board system with an extension for the programmable loads. Due to the problem of dimension increase, two methods have been presented and tested to perform optimal energy management (EM) aboard an aircraft: the Branch and Bound (B&B) and the Linear Regression Approximation (LRA). Finally, numerical simulations and results have been provided to validate the proposed optimization methodologies, according to the dimensions and the complexity of the problem.

“…The access of large-scale new energy, such as wind power, into the grid will lead to changes in the transient stability characteristics of the power grid. For a specific power grid, due to the difference in the access location and capacity of wind and PV power generation stations, the transient stability margin of the power grid is different in different regions [1][2] . Therefore, for the power grid after large-scale access to new energy, the transient stability margin evaluation method of the power grid considering the location and capacity of new energy access is given [3] .…”

This paper focuses on the potential local voltage stability risks and transient stability margin decline in the power grid after the large-scale integration of new energy. Based on the transient stability margin index of the power grid, a method for evaluating and optimizing the transient stability margin after the integration of wind power into the power grid is proposed. This paper provides guidance for the grid connection points and voltage level determination of the wind power access system during the planning phase, as well as the configuration of reactive power compensation devices such as SVGs.
