In July 2019, JSC "NBI" completed the implementation of an optimization system at the Novo-Salavat CHP plant.
The main goal of the project is the modernization of the software and hardware complex, aimed at supplementing the mathematical techno-economic model of the CHP plant with a new combined-cycle unit.
As a result, users across the entire station gained the following capabilities:
− Optimize the operating modes of CHP equipment based on the criterion of maximizing the station’s marginal income, taking into account DAM price forecasts;
− Optimize the load distribution of operating equipment in accordance with a given dispatch schedule based on marginal income maximization;
− Select the optimal equipment composition and calculate the optimal load distribution among units;
− Calculate lost profits due to urgent and emergency repairs that lead to generation equipment constraints;
− Calculate fuel cost increases considering changes in fuel composition;
− Determine the optimal Pmin and Pmax while ensuring heat supply and meeting the electrical load dispatch schedule;
− Model, using specialized components and with specified accuracy, the production processes of heat and electricity generation and supply by the station as a whole;
− Enable the correction of energy characteristics of individual equipment types during system operation;
− Plan and optimize fuel consumption;
− Provide information for forming optimal bids for the wholesale market (DAM, BM);
− Generate reports for a user-specified time period according to predefined and custom formats;
− Allow users to create and store their own simulation modes in the system for further analysis.
The upgraded system enabled the customer to optimally plan operating modes across various wholesale market planning sectors for the entire station, including the new combined-cycle unit. Additionally, functionality was implemented to calculate metrics required for forming optimal price bids in the DAM.
Client: LLC "Novo-Salavat CHP" is the primary source of heat and power supply for the petrochemical complex LLC "Gazprom neftekhim Salavat". Installed electrical capacity – 882 MW; Installed thermal capacity – 2,429 Gcal/h.
