Scenarios for Integration of Power to Heat Technology in Czech District Heating Systems
Abstract
The paper addresses the sustainability of the operation of existing district heating (DH) systems in the Czech Republic, which historically used primarily fossil fuel sources and currently are under transformation. The system integration of heat with electricity sector through power to heat (P2H) technologies allows for the efficient use of DH thermal capacity to store surplus renewable energy and can also offer additional support services to the electricity transmission system. Simulation study was performed in TRNSYS for three typical typologies of DH systems in the Czech Republic. Key performance indicators (KPIs) such as CO2 emissions, non-renewable energy or the cost of heat produced by P2H technology were assessed.
