The objective of this dissertation is to design a novel time varying, half an hour based
electricity tariff for end customers of a microgrid. With the depletion of conventional
energy sources and higher requirement for a clean and sustainable generation, a clear
trend towards distributed generations, and an emphasis on power quality and system
stability has spurred a shift toward a more decentralized, distributed power grid. The
high penetration on renewable energy sources in a microgrid has also caused a new
problem. All of the renewable energy sources are intermittent and uncontrollable to
some extent, that is, peak power generation is not unnecessarily comes with the peak
demand and it is also impossible to fix their power generation to the rated power. Thus,
considerable capacity and energy storages system are needed to ensure the reliability of
the system. However, during the off-peak period when load demand is low, these
capacities is in idle, which will cause an unfavorable waste of resources and increase
the initial capital investment. In order to reduce the peak electricity demand and grant
the demand with ability to track and follow the power generation curve, a novel ToU
pricing scheme is designed by using model predictive control (MPC).
In order to implement the MPC algorithm, power generation and load forecasting
models are studied. The developed models are programmed using Nl LabVIEW and
simulated with history data collected from solar array installed on the rooftop of School
of Electrical and Electronic Engineering (EEE) building and Wee Kim Wee School of
Communication and Information (WKWSCI) building in Nanyang Technological
University accordingly. The power generation model and load forecasting model are
integrated into the MPC algorithm for developing the ToU pricing model.
The developed ToU pricing model is programmed and simulated using NI Lab VIEW.
The simulation results show that the proposed ToU pricing scheme can efficiently
reduce the peak electricity demand and grant the load demand curve with the ability of
track and follow the power generation curve. |
