Chapter 13 Stability Analysis of Grid-Connected Photovoltaic Systems .............................................................. 254 M. A. Mahmud, The University of New South Wales at Australian Defence Force Academy, Australia M. Jahangir Hossain, The University of Queensland, Australia H. R. Pota, The University of New South Wales at Australian Defence Force Academy, Australia This chapter presents an overview Photovoltaic (PV) power generation and integration of PV systems with power grid. This chapter also presents a Feedback Linearizing Current Controller (FBLCC) to synchronize the PV system with the grid. This controller is designed based on the feedback lineariza- tion technique. The reference current for the controller is generated from the Maximum Power Point Tracker (MPPT). The stability of a single-phase grid connected PV system is analyzed through the Lyapunov function. To do these things, a suitable mathematical model of grid-connected PV system is also presented in this chapter. The performance of the designed controller is tested on a single-phase grid-connected PV system. Chapter 14 Energy from Waste: Present Scenario, Challenges, and Future Prospects towards Sustainable Development ....................................................................................................................................... 271 Kalpana Arora, Indian Institute of Technology, India Ashwani Kumar, Indian Institute of Technology, India Satyawati Sharma, Indian Institute of Technology, India Considering the confrontation of waste disposal and minimizing Green House Gas (GHG) emission, technologies of Waste To Energy (WTE) production seem appealing. It provides one key solution for two major concerns regarding energy crisis and waste management. Energy from biomass can be seen as a promising alternative for fossil fuels, which are getting scarce and more costly day by day. Since a significant amount of organic waste from agriculture, industries, and community sources is collected
