Impact Analysis of Renewable Energy Accommodation Considering Heat Pump in Peak Shaving

With the expansion of the installed capacity of renewable energy (RE), the accommodation of RE has not been completely solved yet. During the heating period in China, the electricity output of combined heat and power (CHP) units is determined by the heating load, which reduces the total shaving capacity and making the wind power accommodation more difficult. Firstly, this paper establishes the operation optimization scheduling model of the integrated electricityheating systems. Then, using the combined heat and power units and heat pumps (HP) as the coupling points of the system, the influence of heat pumps on renewable energy accommodation is analyzed based on the traditional heating network model. Finally, numerical tests are conducted on the system constructed by IEEE 33-bus distribution network and Barry Island 33-bus heat system. By comparing different results of different scenarios, this paper discusses the influence of heat pump before and after connecting to the system on the operation of each units and grid-connected wind power. It is obviously that considering heat pumps in peak shaving can improve the capacity of renewable energy accommodation.
