“Province-City-County” Three-Level Renewable Energy Consumption Computation Methods based on Renewable Energy Cloud Platform

Renewable Energy Cloud Platform is a renewable energy industrial Internet platform that applies new generation information technologies into renewable energy business. In order to better carry out the development planning of wind power and photovoltaic, this paper proposes “province-city-county” three-level renewable energy consumption computation method based on the renewable energy cloud platform. The proposed method follows the idea of “whole-to-partial”. The provincial-level consumption model considers the constraints of power balance, system reserve capacity, thermal power unit output, thermal power unit climbing, and renewable energy output etc. The city-level consumption model considers the constraints of line capacity and substation capacity. The county-level consumption model considers the constraints of independent installed capacity, short-circuit current, voltage deviation and harmonic. Case study on a practical power grid in China shows that the proposed method can be used for renewable energy planning and provide support for the implementation of national renewable energy quota policy.
