Abstract
This paper investigates the possibility of applying electric
heat pumps with the control-by-price-concept in order to
avoid overload in a local distribution system. The proposed control
algorithm is based upon a centrally dispatched real-time
market price, reflecting the state of a larger power system, and is
extended with a local price control for overload elimination on
the corresponding feeder. The paper presents the mathematical
models of a two-node system with price-responsive heat pumps,
the chosen methodology of the central price calculation, and the
proposed local feedback control architecture. The simulations of
overload elimination have been carried out in Matlab. The results
show the possibility of such auxiliary service by flexible units,
which could be used for peak shaving in order to minimize the
necessary oversizing of the power system components.
