Abstract

The invention belongs to the field of power systems, and particularly relates to a power grid new energy power system economic characteristic optimization method, which comprises the following steps: acquiring a source grid load storage coordination key technology; determining the weight of the key technology according to the operation cost of the key technology characteristics for the energy internet; and after calculating the total score of the key technology according to the weight, sorting to determine the optimal key technology. The method can provide a theoretical basis for a power grid company to evaluate economic feasibility of large-scale new energy power supply access to a power grid, and can effectively inspect rationality of new energy power operation.

Description

technical field [0001] The invention belongs to the field of power systems, and specifically relates to a method for optimizing the economic characteristics of a grid new energy power system. Background technique [0002] Considering that renewable energy such as wind energy and light energy is very abundant, and has the characteristics of vast land and sparse population, it has the natural conditions and base foundation for building a large-scale renewable energy base. The power system is an important carrier of energy interconnection. Gansu Province's new energy Internet power system facing the global energy Internet needs key technologies to improve the flexibility of the system, and also take into account economic operation. [0003] The integration of information flow and energy flow, the access of various types of energy sources, and the laying of more complex power grid networks across borders are all challenges that the power system needs to face and problems that ne...
