Short-term scheduling of combined heat and power generation units in the presence of demand response programs

Yearly generation maintenance scheduling (GMS) of generation units is important in each system such as combined heat and power (CHP)-based systems to decrease sudden failures and premature degradation of units. Imposing repair costs and reliability deterioration of system are the consequences of ignoring the GMS program. In this regard, this research accomplishes GMS inside CHP-based systems in order to determine the optimal intervals for predetermined maintenance required duration of CHPs and other units. In this paper, cost minimization is targeted, and violation of units’ technical constraints like feasible operation region of CHPs and power/heat demand balances are avoided by considering related constraints. Demand-response-based short-term generation scheduling is accomplished in this paper considering the maintenance intervals obtained in the long-term plan. Numerical simulation is performed and discussed in detail to evaluate the application of the suggested mixed-integer quadratic programming model that implemented in the General Algebraic Modeling System software package for optimization. Numerical simulation is performed to justify the model effectiveness. The results reveal that long-term maintenance scheduling considerably impacts short-term generation scheduling and total operation cost. Additionally, it is found that the demand response is effective from the cost perspective and changes the generation schedule.

Electricity demand response is the lever of economy and contradictions between the supply and demand, is effective short-term instruments that speedy resolve contradictions between the supply and demand [1]. Put forward the elements and implementation principle of demand response programs, divide the type of demand response programs, investigate the time span relationship between demand response market and demand response programs, analyze demand response programs in the practice of domestic and foreign, discuss the application strategy of demand response in large public buildings systems and energy management platform, and for the construction of China's demand response programs raise suggestions and ideas.
