Low-carbon Economic Optimal Operation of Biomass Gasification Hybrid Energy System Considering Electricity-Thermal Flexible Load

Considering an economic low-carbon model and flexible load were used to evaluate advantages in a biomass gasification integrated HES (hybrid energy system) providing multiple energy sources. The HES includes a biomass powered combined heat and power unit, distributed wind turbines, photovoltaic modules, battery storage). Then, under the conditions of energy balance constraints, operation constraints and energy exchange constraints with the goal of minimal economic cost. The assumed energy load is used to analysis the study, which turns out that compared to traditional CHP (combined heat and power), the BCHP (Biomass-fueled combined heat and power) has the more economical and low-carbon performance. The flexible load of electricity and heat can relieve the pressure on the power grid and reduce the economic cost of users during peak periods.
