微网中虚拟同步发电机技术研究
Research on the Virtual Synchronous Generator in Microgrid
摘要
Abstract
Taking the 3#microgrid in the demoretration project of multi-energy,complementary active distribution network of national energy adminsitration as the object of study,the technology of VSG in photovoltaic and energy storage microgrid systems was studied. The principle,topology and control scheme of the VSG were introduced. The power control method of the virtual power was designed,and the voltage outer loop characteristic of the stator electric equation was analyzed. In order to meet the needs of two aspects of VSG frequency modulation and dynamic performance,a parameter design constraint was proposed to ensure that VSG has good dynamic characteristics while satisfying frequency modulation performance requirements;aiming at the microgrid composed of 150 kW photovoltaic and 400 kW energy storage,100 kW VSG,experiments such as black start,planned off/grid switching,unplanned off/grid switching were carried out to verify the reliability of the VSG scheme adopted.关键词
