Across the world, efforts to support energy transition and halt climate change have resulted in significant growth of number renewable distributed generators (DGs) installed over last decade, among which photovoltaic (PV) systems are fastest growing technology. However, high PV penetration electricity grid is known lead numerous operational problems such as voltage fluctuations line congestions...

Many industrial installations in developing countries start-up as small factories, without regard for the need of compensation reactive power, leading to significant financial losses long term. By improving power factor, customer can reduce its demand and potentially increase efficiency their equipment. A PIC microcontroller is used switch capacitor banks compensate power. In order determine si...

This paper describes optimal reactive power control of a doubly fed induction generator (DFIG), which is widely used in a distributed generating plant. Although its structure is similar to that of an induction motor, its reactive power control is more complicated. In this paper, steady-state power transfer equations are derived and developed for a doubly fed structure of the induction generator...

Abstract For getting the reactive power control model parameters of PV inverters, a method was proposed to test and identify fault inverters based on symmetric asymmetric sets. Firstly, structure grid-connected inverter is analyzed, be identified are defined. subsequently, according various types amplitudes voltage that may occur in course operation system, overall data set obtained, given by m...

The increasing proliferation of distributed energy resources has posed new challenges to Volt/VAr control problems in distribution networks. To this end, paper proposes an automatic self-adaptive local voltage (ASALVC) by locally controlling VAr outputs resources. In ASALVC strategy, each bus agent can and dynamically adjust its droop function accordance with time-varying system changes. is ass...
