Abstract
Trends of energy consumption and global warming, air pollution, Greenhouse gas emission, depletion of fossil energy resourcec and the rise in costs of fossil resources, indicate that renewable energies are reliable alternative in energy supply systems. The purpose of the project is to investigate the contribution of renewable energy to meeting energy demand of housing units. Household energy system consists of various parts which do intreract with each other. Total household energy system may be represented with the help of reference energy system in order to consider the effect of changes in one part on the other sections. In this regard, the reference diagram of household energy supply...
Decentralized Active Power Management in PV/Battery Hybrid Source Islanded Microgrids
, Ph.D. Dissertation Sharif University of Technology ; Oraee, Hashem (Supervisor)
Abstract
Due to environmental concerns and continuous decrease in the price, photovoltaic (PV) generations have been increasing in the recent years. PV units can operate in grid-connected or islanded modes. In grid-connected mode, the PV unit delivers its generated power to the grid; on the other hand, in islanded mode, it supplies the local loads. In this research, a new decentralized power management and load sharing method for a photovoltaic based islanded microgrid consisting of various PV units, battery units and hybrid PV/battery units is proposed. Unlike the previous methods in the literature, there is no need to communication among the units and the proposed method is not limited to the...
