Operating Characteristics And Influence On Power Grid With Distributed Electric Heating Considering Load Transfer

Aiming at the issue in vigorously developing distributed electric heating in the north, high simultaneity of electric heating load is easy to cause seasonal power supply insufficiency of grid, load transfer characteristics of three types of distributed electric heating equipment, such as direct heating type, heat accumulation type and air-source heat pump, is compared, and influence of different load transfer characteristics on load rate and voltage quality is analyzed. The heat load is simulated through Markov chain Monte Carlo model. Taking typical village electric heating topology as example, load transfer characteristics of different type of electric heating device is simulated and analyzed on Power factory software platform. Result of simulation proved that load transfer optimizes grid voltage level and transformer load rate.
