N2 - This work considers the operation of the electric power system (EPS) in coordination with the water distribution system (WDS) during extreme operating condition scenarios. The interdependencies are captured by modeling the main dependency of the WDS on the EPS, power for WDS pumps, as well as the main dependency of the EPS on the WDS, the need for cooling water for conventional thermoelectric generation, in simulation. The extreme scenarios include studying the effect of droughts (water shortages) in the WDS and electrical power outages of WDS pumping stations in the EPS. Appropriate network models and mathematical formulations for optimizing control of the operation in the power system with consideration of the present operating conditions in the WDS are presented. These include a novel optimal power flow model for unit dispatch, a model for systematically derating thermoelectric generation during periods of droughts as well as a method for adjusting the cooling water demands of that generation within the WDS. The implementation of these policies is seen to increase the duration for which conventional thermoelectric generation is available for dispatch during such extreme conditions.
