In this paper a fuzzy logic (FL) based load frequency controller (LFC) called discrete FuzzyP+FuzzyI+FuzzyD (FP+FI+FD) is proposed to ensure the stability of a multi-source power system in restructured environment. The whale optimization algorithm (WOA) is used for optimum designing the proposed control strategy to reduce fuzzy system effort and achieve the best performance of LFC task. Further...

This paper demonstrates an enhancement of power quality in grid integrated systems with the help of the proposed control strategy for voltage source converter based active power filters. The Shunt Active Power filters (SAPF) are extensively utilized in modern grid integrated systems to diminish the power quality concerns associated with it. The SAPF is one of the various power filters, which ha...

One of the key challenges of employing photovoltaic systems is to extract maximum power of the panels. This problem is known as maximum power point tracking (MPPT) technique. The MPPT stands for establishing situation in which output power of the panels reaches its maximum allowable power. In this context, this paper is to assess the technical requirements to achieve maximum output power of a n...

An optimal dispatching strategy for a multi-source complementary power generation system taking source–load uncertainty into account is proposed, in order to address the effects of large-scale intermittent renewable energy consumption and load instability on grid dispatching. The problem first converted common situations study, such as forecasting solar wind power. backward scenario reduction L...

In this paper a multi-variable LPV/H∞ control approach is applied to design a strategy for power source coordination within a multi-source energy system. Three different kinds of power sources – fuel cell, battery and ultracapacitor – compose the power supply system of an electric vehicle. All sources are current-controlled and paralleled together with their associated DC-DC converters on a com...
