An innovative technique for optimization and sensitivity analysis of a PV/DG/BESS based on converged Henry gas solubility optimizer: A case study

Abstract

The construction of hybrid power plants with renewable resources can bring significant economic benefits if it is evaluated economically and technically. The present study uses a novel optimum methodology for designing a combined solar/battery/diesel system in Yarkant, Xinjiang Uyghur Autonomous Region of China. In the desired system, the green energy combined system is designed to reduce the use of diesel generators. The diesel generator has been used in the photovoltaic, diesel, and battery to support green energy resources and batteries, as well as function as a backup generator for critical times whenever the production of green energy resources is low or the load demand is high. The amount of CO2 emitted, the probability of load shortage and the system cost on yearly basis are the major goals in the process of optimization. Here, the single‐objective problem is created by using the ε‐constraint technique to combine the many objectives. An improved Henry gas solubility optimizer handles the problem of optimization. To demonstrate the superiority of the strategy, a comparison is conducted between the simulation outcomes of the offered system, HOMER, and particle swarm optimizer ‐based optimum systems from the literature. The sensitivity of each parameter is also examined using sensitivity analysis.

A new optimal energy management strategy of microgrids using chaotic map‐based chameleon swarm algorithm

“…In the present study, SOFC, which stands for solid oxide fuel cell, has been utilized. Equation () can be used to characterize a one‐cell solid oxide fuel cell's output voltage [31]: $$$$\begin{equation}{E_{\textit{FC}}} = {E_{Nernst}} - {V_{conc}} - {V_{{\Omega}}} - {V_{act}}\end{equation}$$$$where $${E_{Nernst}}$$ describes the Nernst reversible voltage. $${V_{conc}}, {V_{{\Omega}}}$$,, and $${V_{act}}$$ represent the concentration, ohmic,, and activation voltage, drops respectively.…”

“…Accordingly, chameleons are able to search every possible location in the solution area. As already mentioned, w 1 and w 2 , in Equation (31), are for controlling the search ability in the CSA. CSA could change between local and global search if small and large numbers are assigned to these parameters.…”

“…In the outset (early steps), all chameleons are far from target. Their position is changed via Equation (31), which increases the ability of the algorithm to explore the area globally. • w 1 and w 2 : alteration of chameleons' the situation is heavily overshadowed by w 1 and w 2 .…”
