IncreasedRESSelfConsumption- description
Short Description
This test case is used to verify that self-consumption of renewable energy sources in a coupled heat and power network improved using distributed power-to-heat appliances compared to a base scenario without power-to-heat. This means that energy flows flowing out of the network are reduced. At the same time energy imports should not increase. Relevant effort variables of both networks, i.e., bus voltages, supply temperatures and differential pressures, must stay within the allowable range. Also, the loading of the transformer is not allowed to reach critical levels. Otherwise the test fails.

Acceptable test result | The power flow to the external grid and the heat flow from the base district heating boiler are reduced compared to a scenario without power-to-heat appliances. Thus, self-consumption of RES is improved. At the same time, the power flow from the external grid is not allowed to increase more than 1%. Moreover, the following technical criterias must be met:
