Abstract The improvement of renewable energy resource-based power plants is a real and modern global challenge, and therefore, biogas applied in reciprocating Internal Combustion Engines is an excellent alternative to this challenging task. Biogas can be obtained from various sources and its composition varies according to the biomass type used in its production, but the majority of this fuel is composed of methane (CH4 ) and carbon dioxide (CO2 ). However, there is no reliable control to hold the power quality following Brazilian Electricity Regulatory Agency (ANEEL) requirements. In such a context, this paper presents four control schemes to assure the power quality by a generator set operating with biogas from wastewater treatment. In order to accomplish it, a mathematical model was developed to represent the mechanical and electrical phenomena involved in the generation process. These control systems were evaluated in load and biogas composition variation scenario at same time in an environment developed in MATLAB/Simulink. The performed tests showed that the scheme composed by two Proportional Integral Derivative in parallel operation switched by fuzzy logic controller with particle swarm optimization tuning is better than all schemes proposed in this work and this layout enables the power plant to remain connected to the grid in all simulation scenario, because power frequency and voltage remained within limits imposed by national standards. Keywords Biogas · Fuzzy logic · Generator set modeling · Particle swarm optimization · Power generation control
1 Introduction The worldwide demand for electricity increases every year [1], and it is increasing even more due to technology advances, so energy-producing in an efficient, reliable, and affordable way is a real and modern challenge [2]. This question coupled with the global warming, climate change, and the need to generate fewer environmental impact, demands robust renewable energy resource (RER)-based on power plants that increase networks reliability and availability, in addition to mitigating the environmental impacts caused by conventional energy production methods [3]. Furthermore, RER-based power plants can generate electricity with low transmission losses, because power generation is closer to consumer centers, characterizing distributed generation (DG) [4]. Among the renewable energies, biogas has enormous potential to increase the share of renewable
