Abstract
This paper investigates impact of integrating a
wave energy converter (WEC) on sizing the battery and solar
panels, and energy management of a microgrid utilising wind,
solar and diesel generator at the generation side. An integrated
co–optimisation model for sizing and energy management is
proposed to minimise the levelised cost of electricity (LCOE)
and dump load ratio (DLR), while maximising the reliability of
power supply. Parasitism predation algorithm is employed to
solve the multi–objective optimisation problem. Moreover, a
repair–based penalty approach is integrated for effective
constraint handling. The Westray Island standalone microgrid
in Scotland is considered as a case study. Annual hourly weather
data and demand profile of Westray Island are used to simulate
the system in MATLAB environment. Results show that the
WEC acts as an energy buffer in the microgrid with about 6%
higher LCOE and 85% higher reliability of the power supply
compared to the case without WEC integration. It also
demonstrates that the diesel generator plays a minor role in the
microgrid with WEC, which further reduces emissions.
However, with the WEC integration, the DLR has increased by
124%, compared to the case without WEC.
