A SUSTAINABLE AND ECONOMICAL MICROGRID DESIGN FOR ELECTRIC POWER DISTRIBUTION OF TKMCE CAMPUS

Abstract

The electric power demand and electricity prices are increasing day by day. The increase in EVs, new automatic machinery and increased load demand puts a high burden on the utility. A localised solution incorporating the areas’ renewable sources is needed to accommodate future demands. The rising demand of electricity in the TKMCE campus and increasing tariffs are a major concern. The aim of this project is to design a Hybrid microgrid architecture using a PV system as renewable resource, incorporate other generation and loads for the TKMCE campus to reduce the future electricity cost. The project cost analysis is also done to analyse the economic viability. Different cases and scenarios are proposed and analysed and study on the existing system, protection, primary control method and the PV system design is done. A droop control method as part of the primary control of the hierarchical control, to share the power between the inverter-based sources and to regulate the voltage and frequency at the PCC bus is designed and simulated. A concept of “Zero electricity bill” and the modifications that needs to be introduced to attain this concept is also proposed.
