The increasing installation of gas-burning (natural gas) power plants1 has increased the integration of natural gas and hydropower2 and fossil networks. Optimum exploitation of these networks has created the need to investigate the interactions between these networks and optimize the management of energy resources from the perspective of centralized planning. Coal is the most abundant fossil fuel on the planet, and is widely used as an energy source in thermal power plants. It is also a relatively cheap fuel and produces more than the equivalent amount of oil or natural gas. he does. On the other hand, hydroelectric power plants do not need fuel and help to preserve the environment and water resources. Gas power plants also supply the most energy in the world after hydroelectric power plants and fossil fuels. On the other hand, multi-energy hubs with tools such as power to gas converters (P to G) that have the ability to convert different types of energy carriers to each other and are considered the meeting point of electricity, water and gas distribution networks. Greenhouse gas emissions in fossil fuel power plants are much higher than gas power plants. The main emissions from coal combustion are sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, and carbon dioxide (CO2). There are also greenhouse gas emissions in gas power plants. But in these power plants, the emission of greenhouse gases is far less than fossil fuel and they are preferred for electricity production. On the other hand, electricity production in natural gas-burning power plants also faces limitations in the cold months of the year, as a result of which the consumption of fossil fuels and the emission of greenhouse gases increase sharply, which, due to the cold weather, causes many problems for the environment provides. In this thesis, an optimal strategy for the integrated and coordinated operation of the water, gas and electricity network is proposed within a period of one year, considering the limitations of all three networks. In the first term, the objective function of the model proposed in this thesis is to minimize the cost of operation and production in all three networks of water, electricity and natural gas, and in the second term, the objective function is to minimize environmental pollution caused by Combustion of coal and natural gas is considered in different months of the year. The proposed model, using a max/max Price Penalty Factor, (PPF) method, tries to reduce environmental pollutants during the cold months of the year, along with reducing the consumption load of the electric and gas network. Since, unlike electric energy, where large-scale storage is not yet technically or economically possible, natural gas can be stored for consumption in different months of the year. The use of natural gas storage resources along with power to gas converters (P to G) has facilitated the achievement of the above goals in the proposed model. By testing the proposed strategy on a mixed system of electric, water and gas networks, the efficiency of the proposed model has been shown.
