An analytical approach to the consideration of the substantial physical and technological links between parameters of interdependent grid elements of a complex water supply system by means of technical economic modeling is presented.An effective use of the intrinsic subsystem of auxiliary equations within productive type models for the material and energy balance in a grid is discovered for the first time. By the example of the hydraulic grid of a water supply system, some methodological features of energy balance estimation within the technical economic model of systems with network structure are described.The consideration of the material and energy balances for the flow distribution in the multiproduct model of electric-power- and water-supply systems allows one to evaluate the impact of operation modes and technological and economic factors of the interacting network systems on the volumes of technological costs and the nodal prices of water and electric power supplies.The possibility to determine the effect of node energies on the nodal prices and to evaluate the energy- and cost-efficiencies of routine and emergency operation modes of a sewerage-pumping plant of the Kiev water-treatment enterprise is demonstrated.
