The invention discloses an energy cloud platform and a data interaction method based on the energy cloud platform and is applied to the cloud platform technology field. The energy cloud platform comprises a data sending/reception interaction unit, a data storage unit, a data attribute information setting unit, a business alarm configuration unit, an information management unit, a data visualization display unit, an API interface unit, a southing interface and a northing interface. According to the energy cloud platform, through change on an interaction mode, interaction with application service is improved, extra specific demands of users in energy industries are satisfied. The energy cloud platform employs ISO/IEC/IEEE 18880 communication standards, consistency of data interaction among the onsite side, the energy cloud platform and an application service APP is guaranteed, a loose coupling mode is realized technically, and robustness and scalability of the whole system are enhanced.
