Abstract

The invention provides an evaluation method and equipment for absorption of a power grid for new energy power generation, and relates to the technical field of new energy power generation. The evaluation method comprises the steps of acquiring data corresponding to the power grid; determining an input state; performing operation simulation on the power grid by adopting a multi-period direct current optimal power flow model considering peak regulation constraints of the power grid according to the input state to acquire an output state of the power grid, wherein the output state of the power grid comprises an economic index, a new energy absorption index and a power grid line utilization index; performing evaluation on the state of the power grid according to the economic index, the new energy absorption index and the power grid line utilization index, and proposing an expansion planning scheme of the power grid according to an evaluation result. According to the invention, the uncertainty of new energy output power can be effectively considered, the output state of the existing power grid is provided quantitatively, evaluation is performed on the state of the power grid by using various indexes, and the total cost of the power grid can be effectively reduced and the new energy absorption level of the power grid can be improved by using the power grid expansion planning scheme proposed under guidance of the state.

Description

technical field [0001] The invention relates to the technical field of energy power generation, in particular to the planning and evaluation technology of new energy, and specifically relates to an evaluation method and equipment for power generation by power grid consumption of new energy. Background technique [0002] This section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In recent years, my country's new energy power generation has developed rapidly. In the first quarter of 2016, my country's new wind power grid-connected capacity was 5.33 million kilowatts. As of the end of March, the cumulative grid-connected capacity reached 134 million kilowatts. At the same time, by the end of 2015, the cumulative installed capacity of photovoltaics in my country exceeded 43GW, surpassing Germany to become the count...
