Optimization of the Electrical production of the electrical groups

The excessive increase in the price of the oil barrel following the economic and political situation brought the public authority to adopt a national strategy of energy saving in order to preserve the energy resources of the country and to rationalise consumption. Among the adopted measures, we indicate theses ones: the production's optimization, the optimization of the transport and distribution of energy, the optimization of consumption... The Tunisian Society of Electricity and gas (STEG) developed various strategies' choices request kind of the production, transport and electricity distribution supporting the competitiveness of its activities in terms of price and Service Quality. The electric effectiveness consists in managing the request electricity while taking care of the production profitability and the energy saving on the consumption level by using as examples the low consumption lamps, the capacitor batteries installation for improving the power-factor and the setting of a new tariff for the reduction of the power during the peak hours. The conversion of the combustion turbines for operation into natural gas was very beneficial for the STEG, this is of the fact particularly of the difference in price between natural gas and the oil gas; moreover, the economic distribution of the energy's production groups is able to reduce the costs without additional loads. The problem consists in optimizing the total specific consumption and consequently the cost of the kilowatt-hour while respecting various constraints of exploitation and safety.
