Standalone hybrid systems are need of the hour in electrical power sector. The reactive power support is most vital issue in the voltage point of view.Wind energy has received the special attention of researchers in recent times. Attempts to generate electricity from wind energy have been made since the end of nineteenth century. A single renewable energy source may not be able to meet the load demands apart from the fact that continuous supply of energy may not be ensured. Here comes the importance of Hybrid energy systems such as Wind-diesel, Wind-PV.Advanced FACTS technologies have utilized for reactive power support to the system. The fuzzy logic has implemented in the control circuit of STATCOM which is relatively advantageous compared to conventional PI controller. The control strategy is verified through model simulation study whose results conform the significance of the control methodology incorporated in the paper.Keywords

Objective: Hibiscus plantifolius is a shrub with various medicinal uses and belongs to the Malvaceae family. The present study is aimed at determining in vivo antioxidant activity of MEHP using the paracetamol-induced hepatotoxicity test in rats. Methods: The animals were randomly divided into 7 experimental groups and administered with test solutions. Rats were divided into seven groups and received 10% DMSO (negative control), Paracetamol (2 gm/kg bd. wt.), Silymarin (10 mg/kg bd.wt.) or 50mg/kg MEHP (50, 150 and 300 mg/kg) orally once daily for 7 consecutive days. The oral administration of paracetamol was performed 3 hours after the last extract administration on the 7th day. The blood and liver tissues were collected and subjected to biochemical and microscopical analysis. Results: In this study, it was observed that MEHP extract significantly (p<0.05) increased hepatic SOD and CAT activities in paracetamol-induced liver damage in rats. The antioxidant activity was exhibited due to presence of flavonoids and tannins, phenolic compounds which was present methanolic extract of Hibiscus plantifolius. Conclusion: The antioxidant activity was exhibited due to presence of flavonoids and tannins, phenolic compounds which was present methanolic extract of Hibiscus plantifolius.Keywords
