Abstract
Integrating intermittent wind and solar energy into hybrid energy system has introduced significant operational uncertainties. This paper develops a static operation model incorporating biomass gasification-based combined heat and power as a coupling center based on conceptual utility grid-connected real data in Sacramento, California. This study involves generating typical scenarios with seasonal characteristics and demand correlations to capture key input parameters accurately. Subsequently, the Newton-Raphson method was developed to calculate the energy flow within these scenarios. Simulation results demonstrate the proposed method achieves over 70 % construction accuracy across different seasonal scenarios. The economic results that the winter electricity loads increased by 44.8 % compared to summer, with corresponding rises in gas and heat loads by 360.6 % and 372.3 %, respectively, resulting in the hybrid energy system economic cost increase of 58.9 %. These results confirm the model's robustness in effectively managing intermittent energy sources and addressing the economic impacts of seasonal demand variations.
期刊介绍:
Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics.
The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management.
Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
