Combined Optimization of District Heating and Electric Power Networks

Abstract

The main contribution of this work is the development of a network operation approach for integrated electric power and district heating networks based on social welfare optimization. Thereby demand-side management and economic dispatch are obtained simultaneously by taking into account consumers, flexible consumers, producers and renewable energy sources and the operational restrictions of both networks. The optimal operation is based on a transactive control approach which is identical to a nonlinear model predictive control problem here. Both energy networks are modeled in an accurate way leading to a nonlinear programming problem. Additionally an extension to the node method is presented.
