INVESTIGATION AND CONTROL OF HYBRID WIND-PV SYSTEM WITH ISOLATED MODE

This paper present hybrid wind-PV-battery system dynamic model developed in MATLAB/Simulink software, the control strategy for energy management proposed by the fuzzy logic ru le viewer. A PV panel, wind panel and dynamic models of lithium-ion storage connected together with the DC link and all these sources are working on the basis of fuzzy rule based control. The DC link is connected through the power electronic interfacing circu it (converters) and converters connected to a source for a diverse electricity generation. All sources work on the basis of the MPPT control algorithm, which will work if and only if the panel operates at the peak point of power generation. The hybrid generation systems that can maintain continuous load power demand and provide satisfied operation on the main constraints. The developed control strategy can control various devices and different power interface circu itry. The main objective of th is thesis is that to ensure a continuous power by coordinating appropriate control strategy with all sources. The simulat ion studies have been carried out to determine system performance with different scenarios of the sources such as typical solar radiation, temperature, air and battery charge or d ischarge conditions. Simulation test results show variable power generation and verify the performance of the integrated system with control strategy is overall effective for real-t ime installation. The developed system is essential in an isolated region where an existing g rid is unable to supply secure power generation and system is beneficial with smartly feed ultimate power generation sources.
