Modelling and Optimization of Park Integrated Energy System with Biogas Considering Dynamic Adjustment of Thermoelectric Ratio

Park Integrated energy system (PIES) changes the traditional mode of independent energy supply, achieves multi energy synergy and mutual assistance, and improves energy utilization efficiency. Biogas, as a renewable energy source, has advantages of promoting wind and solar energy consumption and reducing natural gas supply pressure. However, there are limitations in the research on biogas utilization in PIES, and its carbon reduction attributes cannot be effectively utilized. The potential of energy-saving regulation by optimized scheduling strategies urgently need to be explored. To solve the above problems, this article establish the system structure of PIES with combined heat and power (CHP) units considering dynamic adjustment of thermoelectric ratio. Through simulation verification, compared with traditional PIES, the model proposed in this article can promote the output of renewable energy units, reduce system carbon emissions, and achieve more economical operation of PIES.
