Background: Antibody-drug conjugate (ADC) is an emerging therapy that bestows advanced breast tumors with encouraging clinical activity and manageable toxicity; however, the outcomes of phase 2/3 randomized controlled trials (RCTs) are heterogeneous. Our study aims to assess utilities [i.e., objective response rate (ORR), benefit (CBR), progression-free survival (PFS), overall (OS)], treatment-...
this paper presents a cooperative control which is applied to the secondary control of a microgrid controlled via a multi-agent scheme. balancing power that leads to voltage and frequency stability in a microgrid is essential. the voltage and frequency regulations are limiting within the specified limits and conveying them to their nominal values. limiting and conveying the voltage and frequenc...
This paper studies microgrids where loads are supplied by parallel connected inverters controlled by decentralized active power/voltage frequency and reactive power/voltage magnitude droop control laws. The implementation of droop control laws for sharing of power between inverters has been known to present stability problems particularly for large values of active power/voltage frequency droop...

The motivation to develop microgrids (MG), as a particular form of active networks is explained and presented as an effective solution for the control of grids. In MGs, with high level of penetration of Distributed Energy Resources, the stability becomes an important issue. Some control characteristics of elements such as droop coefficients in VSI highly affect voltage and frequency stability. ...
The growing interest in sharing the renewable-energy resources in power microgrids presents major challenge from the perspective of reliable operation and control of the power systems. The issue of the microgrids autonomous control has received a considerable attention in the last decade. As the architecture of the power system control, a hierarchical control scheme can be implemented for the i...
: This paper proposes an autonomous and economic droop control scheme for DC microgrid application. In this method, a cost-effective power sharing technique among various types of DG units is properly adopted. The droop settings are determined based on an algorithm to individually manage the power management without any complicated optimization methods commonly applied in the centralized contro...
Microgrids are nowadays used to produce electric energy with more efficiency and advantage. However, the use of microgrids presents some challenges. One of the main problems of the microgrids widely used in electrical power systems is the control of voltage, frequency and load sharing balance among inverter- based distributed generators (DGs) in islanded mode. Droop method performance degra...
Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...
In this paper, we analyze one of the main drawbacks of droop control-based DC microgrid systems, and propose a novel control method to overcome this problem. Typically, DC microgrid systems use droop control techniques to enable communication independency and expandability. However, as these advantages are based on bus quality and regulation abandonment, droop-based schemes have limitations in ...
