Through the summary and analysis of the factors affecting the stability
and energy-saving of distributed power system, the article, finds out the common
influencing factors, namely the zero pressure difference point and pump selection. The
results show that when the zero pressure difference point is close to the heat source, it
is good for the stability and energy-saving of the system. It’s better to select steep type’s
pump for the main circulating pump and flat type’s pump for users.
