Study on effect of bypass pipe regulation in heating systems on renewable power consumption in integrated electricity and heat energy system

When quality-quantity regulation is adopted in heating systems, adding bypass pipes with electric valves in heating networks can increase the number of control variables, which can improve operation flexibility of integrated electricity and heat energy systems (IEHS). An optimal scheduling model of IEHS is established in this paper and the impact of bypass pipes regulation on renewable power consumption is studied. A sequential solution method combining linear optimization and nonlinear optimization methods is established to handle the non-convex and nonlinear characteristics of the scheduling model. Finally, the effectiveness of the method is verified in a case study. Results show that bypass pipes in heating systems can promote renewable power consumption.
