For solving the synergetic load forecasting problem between superior and subordinate network in the process of city network planning, a B/S based city power network load forecasting management system was developed with the theoretical framework of the computer supported cooperative work (CSCW). A load forecasting workflow model, which is fit for several departments, was set up based on the built-in visualization workflow customizing tool of the system. Synchronously, the system implements several functions such as data flowing, summarization and balance, storage, release and so on. With a method for synergetic load forecasting based on maximum entropy principle, the system realizes synergetic load forecasting between superior and subordinate. In addition, the seamless integration between management system and the decision-making support system was realized based on the planning CIM interface and a synergetic load forecasting information platform was formed, which covers all the load forecasting business. Practical application shows that the platform can strengthen communication between superior and subordinate, optimize load forecasting business, normalize data collection and distribution and improve the efficiency of load forecasting remarkably.
