Abstract [en]

Existence of integrated approach in supplying a local community with its energy requirements from renewable energy or high-efficient co-generation energy sources has come to stay in Sweden. However, in response to the goal of maximizing profit on heat and electricity production with such approach, it then becomes important for combined heat and power (CHP) plants operators to fine-tune their production to adequately fulfil this goal. ENA Energi AB initiated this study on district heating (DH) system as a step in achieving this huge aim.

This master’s thesis focussed basically on relationship and variations of the district heating supply temperature with other variables that affects electricity and heat production in the plant; validation attempt was also carried out on the plant’s model based on some data simulation on the model.

In view of these, minimizing the district heating supply temperature with increasing heat flow was observed as a vital step towards maximizing heat and electricity production for this plant in order to meet the customer’s demand. More so, the plant model was confirmed valid for a certain temperature limit, therefore, based on the findings, the relationship and the model could be used in decision making for the daily operations for the plant.

Keywords: District heating, Electricity, Supply and Return temperature, Heat load and Accumulator
