Increasing the integration of variable renewable energy in coal-based energy system using power to heat technologies

The transition of the entirely coal-based energy system towards one focused on the maximum share of renewables presents a challenge that requires sector coupling and integrating new technologies within the heating, cooling, electricity and transport sectors. The goal of this work is to identify the influence which utilization of district heating systems coupled with the power-to-heat technologies based on the flexible operation of coal-based thermal power plants and limited electricity system interconnections can have on the maximum integration of variable renewables. An hourly deterministic tool Energy PLAN, which is used for the analysis of complex energy systems, was used for modelling and simulation of Kosovo energy system. District heating covering 50% share of total heat demand is used as input data in the model for the analysis of the effect that economically viable district heating systems and power-to-heat technologies can have in increasing renewable energy penetration in coal-based power systems. Results obtained have proved that power-to-heat technologies have a significant impact especially for increasing the wind power with less contribution of solar PV power penetration.
