Modelling of an innovative and autonomous micro-grid based on a biomass - solar PV hybrid power system

Micro-Combined heat and power (m-CHP) systems fuelled by renewables, such as residual biomasses, are today of great interest to produce energy in an efficient green way. The aim the present work is develop a numerical model hybrid system including biomass powered m-CHP unit based on gasification coupled with solar photovoltaic (PV) modules electrical storage device, able provide remote areas. Main advantages considered configuration its ultra-low environmental impact just autonomous operation local resources. developed unsteady multiphysical accounts for main plant components, namely syngas engine, PV panels battery, well dynamic use produced energy. features adopted schematization actual rely proper description combustion, that takes into account extreme difficulty working non-conventional gas, PID control flow management meet demand curve. panel current calculated through ad-hoc function reads, at any given time, irradiance data city Naples, Italy, battery voltage parameters module. 48V capacity 100kWh, modelled equivalent circuit State Charge (SoC) versus Open Circuit Voltage (OCV) response particular SoC temperature calculated. This modelling permits optimal whole thermal user’s also better design possible change or size specific real uses
