This study presents technical issues to enhance the micro‐grids (MGs) performance. Novel distributed flexible AC transmission system (D‐FACTS) is applied on AC/DC MGs to achieve full utilization of distributed generations (DGs), and to improve power quality and system stability. That D‐FACTS is called green plug‐energy economizer (GP‐EE) device, which is proposed with two schemes to be applied on both DC/AC terminals of MG. DGs are used within MGs so that they can meet dynamic load patterns. Proposed design of MG includes photovoltaic, fuel cell, battery, storage system, micro‐gas turbine and wind turbine. GP‐EE device will be controlled by PID modified weighted controller. Dynamic tri‐loop error driven will be enhanced by extra supplementary regulation loops to ensure power factor correction, stabilize buses voltage, reduce feeder losses and power quality enhancement. A recent heuristic optimization technique is called backtracking search algorithm, and is proposed for optimal selection of the scheme parameters of pulse‐width modulation pulsing stage of GP‐EE to dynamically online gains adjustment of PID tri‐loop regulation process and minimization of the global control error. Digital simulations have been validated GP‐EE schemes effectiveness based on without and with modules performance. Achieved results show applicability and improved performance using the proposed technique.
