In this paper, a small-scale plant operating in stand-alone mode, powered by a micro gas turbine and a solar system, is proposed and analyzed. The main consideration in this perspective is environmental sustainability, which drives the use of renewable energy sources such as solar energy and biomass. In this research, the proposed system comprises solar panels, a micro gas turbine and a battery. The gas turbine is fed by syngas generated by a gasifier, on its turn supplied by biomass. The biomass used consists of waste from food production, such as olive pits. The gas turbine, battery, gasifier and gas tank, together with their auxiliary devices, were modelled following the methodologies described in the technical literature and an in-house simulation code is suitably written. It includes a control system to manage the allocation of demand among solar energy, the gas turbine, and the battery. The aim is to keep the gas turbine away from low-efficiency conditions, while also taking into account the state of charge of the battery to avoid values that are either too low or too high. Initial results suggest a promising potential, with a preliminary analysis indicating a possible fuel (biomass) saving up to 15%. Potential improvements are currently under investigation.

Abstract
In this paper, a small-scale plant operating in stand-alone mode, powered by a micro gas turbine and a solar system, is proposed and analyzed. The main consideration in this perspective is environmental sustainability, which drives the use of renewable energy sources such as solar energy and biomass. In this research, the proposed system comprises solar panels, a micro gas turbine and a battery. The gas turbine is fed by syngas generated by a gasifier, on its turn supplied by biomass. The biomass used consists of waste from food production, such as olive pits. The gas turbine, battery, gasifier and gas tank, together with their auxiliary devices, were modelled following the methodologies described in the technical literature and an in-house simulation code is suitably written. It includes a control system to manage the allocation of demand among solar energy, the gas turbine, and the battery. The aim is to keep the gas turbine away from low-efficiency conditions, while also taking into account the state of charge of the battery to avoid values that are either too low or too high. Initial results suggest a promising potential, with a preliminary analysis indicating a possible fuel (biomass) saving up to 15%. Potential improvements are currently under investigation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
