Abstract:Under the current situation of energy transformation and power system reform, it is an inevitable choice for power grid enterprises to transform and develop integrated energy services. At the same time, with the development of energy Internet technology, the interconnection of energy, energy and information integration has been further strengthened, which has made it possible to develop integrated energy services. The grid enterprises carry out comprehensive energy services to meet the needs of customers, and the market has huge scum strength, which is an important profit in the future. How to give full play to the advantages of power grid enterprises, use Internet thinking, promote the modularization of a variety of new energy sources, and source, network, load and store multiple energy sources. Deep integration, expand a variety of new business models, tailor-made energy products and service matching solutions for users, is the current power grid enterprise. The primary issue for transitioning integrated energy service providers. This paper proposes an extended ewton-Raphson integrated energy system steady-state multi-energy flow calculation method for IES, and builds a unified heterogeneous energy flow unified scheduling model for integrated energy systems. By combining the more successful business models implemented in the current power market reform environment with the integrated energy platform, a new type of business model with a high variety can be developed to form a comprehensive energy industry chain from production to consumption to value-added services.
