NPC. As Table 8 is also shown, using PEV and wind turbine is two
first choices for increasing RER, and the next option would be using
a biomass boiler. In the solution 3, RER is obtained as 100% by
installing a 73 kW wind turbine, 200 kW biomass boiler, and using
PEV. In the solution 4, RER is achieved as 100% the same as the
solution 3 while its LLP (3.4%) is lower than the solution 3 and CO2
emission is reduced to 1 ton/year.
The empirical studies are also implemented to analyze the
performance of the proposed DMOPSO. It is compared to two of
most well-known multi-objective optimization algorithms which
are multi-objective genetic algorithm (MOGA) [41] and multiobjective
particle swarm optimization (MOPSO) [42]. All three algorithms
are implemented in Cþþ programming environment, and
then for statistical analysis purpose, each algorithm is run for 10
times. The results of coded algorithms are compared with each
other based on some popular performance metrics explained in
section 5. The experimental results are presented in Fig. 13, Fig. 14,
and Table 9 to clarify the performance of the employed algorithm. It
