Abstract:Cogeneration is currently one of the cheapest ways to generate electricity. The European Union promotes systems for combined heat and power generation. In Europe in general – and Poland in particular – there are numerous district heating systems powered by CHP plants. Most plants are equipped with back-pressure turbines. Energy conversion efficiency for this class of installations reaches approximately 80%. The main disadvantage of cogeneration is that electricity production is directly related to heat production (i.e. demand). The load curve of the heating system varies depending on the time of day, day of the week, and season. On the daily scale the largest heat demand is observed at night and smallest during the day. This study proposes a mathematical model to plan out a large CHP plant with a heat storage tank to be used for the purposes of operational optimisation. Potential increases in profits from electricity sales enabled by the heat accumulator are also quantified.
