Embodiment

[0164] The technical solution realized by the present invention will be further described in detail below in conjunction with a preferred embodiment.

[0165] Simulation example system such as Figure 4 As shown, the provincial regional power grid is divided into 6 regional sub-grids. The planned horizontal year conventional power installed capacity is 31.5GW, the maximum load is 14.2GW, and the high-voltage DC external transmission power is considered to be 12GW during the day and 8.4GW at night. The output range of the thermal power unit is, non-heating period: the minimum output of the thermal power unit is 60% of the rated capacity, and the maximum output is 95% of the rated capacity; the heating period: the minimum output of the heating unit is 85% of the rated capacity, and the maximum output is 95% of rated capacity.

[0166] First, under the condition of 9GW of new energy installed capacity (7GW of wind power and 2GW of photovoltaic power), the time-series production ...

Abstract

The present invention relates to an area new energy development scale and layout analysis method based on power grid constraint. The method comprises the steps of establishing an area new energy development model based on the electric power system production simulation, establishing a new energy consumption level measurement index, optimizing a conventional power supply power on combination considering the safety constraint, researching the electric power system production simulation, and analyzing the new energy development scale, the new energy electric quantity consumption and the conventional power supply operation cases in a continuous time sequence. On the above basis, a sensitivity analysis is carried out based on the static voltage stability, a wind power development scale capacity distribution research method is provided, and an area power grid new energy development layout is optimized. The method of the present invention completes a new energy grid connected consumption research method system, and provides the technical supporting for the large scale new energy development and planning.

Description

technical field [0001] The invention relates to a method in the field of new energy planning in new energy power generation technology, in particular to a method for analyzing the scale and layout of regional new energy development based on grid constraints. Background technique [0002] At present, time series-based production simulation for power system scheduling is widely used in power balance and generation production planning. Time-series-based production simulation refers to a time-series simulation method that simulates the operating conditions of each generating set and calculates the production cost of the power generation system under a given load condition. The system load and new energy power generation output are regarded as a time series that changes with time, and the characteristics of time series changes can be calculated. The balance relationship between system load and unit output is regarded as the supply-demand balance relationship between product and ...
