Design and Development of Nanogrid for Distributive Energy Resources
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryFor designing of DC Microgrid different architectures are used, considering efficiency factor we are using distributed generation and distributed storage architecture. A nanogrid is a small version of DC microgrid which distribute electricity which is commonly used from distributed energy resources. The mandatory components of a nanogrid are renewable energy sources, localized storage units (batteries), power converters, control algorithms and monitoring system. It supplies power directly to the localized load and DC microgrid. By using bidirectional converter nanogrid can be connected to DC microgrid or it will be operated in islanded mode. To achieve power balance, efficiency and stability different control algorithms are used to control the power share between load, nanogrid and microgrid. The prime aim of this project is to design and develop a nanogrid to efficiently extract electrical power from renewable energy resources like PV panels using MPPT, properly utilize it for local load and transmit the surplus power to the DC microgrid.
