AN TWIN PEAK BASED FLC FOR MICRO-GRID CONNECTED INTEGRATED HYBRID RENEWABLE SYSTEM

Abstract

In this paper, the design of a micro-grid power
system supplied from different hybrid renewable energy
resource is proposed. The proposed system provides a highly
efficient key for energy management, control and operation
of micro-grid fed from hybrid energy resources like wind,
solar, fuel battery and ultra-capacitor. Maximum Power
Point Tracker (MPPT) is designed so as to attain maximum
power output from the solar photo voltaic (PV) panel
systems. The novelty of the proposed system fabrication in
the method of Luo Converter for dc-dc conversion as
opposed to single-ended primary inductor converter
(SEPIC). A Twin Peak Detection (TPD) algorithm was
introduced to determine the maximum output of renewable
energy source for connect to the micro grid and other source
for storage system. The Fuzzy Logic Controller (FLC)
generates the signals to the converter based on the source
and energy demand. The performance of the hybrid system
was evaluated by simulating the models of individual units
like PV panels, wind turbine, fuel, battery system and ultracapacitor
under different operating conditions.
