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.
