Thermal energy storage for CHP in power market conditions

About 8% of all the world's electricity is generated by means of combined heat and power plants (CHPPs). At the conditions of an open market, the operation of the CHPP according to the heat load chart means that the generated electricity is not sold at the most profitable prices at the exchange. This is due to the fact that the time of the maximum electricity price does not coincide with the time of the maximum heat load for the CHPP. In the present article, an attempt will be made, by means of simulation, to assess what kind of thermal storage is taking place at the multi-apartment buildings of the city of Riga that are connected to the district heating system and how this will allow shifting the heat load chart for Riga CHPPs at the conditions of the Nord Pool electricity market.
