摘要:

中长期交易电量日益增多，电网可调节裕度减少，因此有必要进行中长期电量安全校核。首先构建电量裕度求解模型，并考虑安全约束必发电量和未来态电网模型，计算机组、断面等关键主体的电量极限。然后通过关联系数矩阵实现中长期电量校核及调整。最后以实际省级电网作为算例，验证所提出模型方法的有效性。通过电力计算、电量校核的方式，为中长期双边交易和电网安全调度运行提供一种技术分析手段。

Abstract:

Medium and long-term trading power is increasing, and the adjustable margin of grid is reduced. Therefore, medium and long-term electric quantity security check is necessary. Considering power quantity constraints and the future state grid model, the power quantity margin solution model is constructed. The power quantity limits of principal equipments such as unit group and line section are calculated, and the medium and long-term electric quantity security check and adjustment are realized through the correlation coefficient matrix. The provincial power grid is used as an example to verify the effectiveness of the proposed model and method. The method of power calculation and electric quantity check provides a technical analysis method for medium and long-term bilateral trading and grid security dispatch operation. This work is supported by Science and Technology Project of State Grid Corporation of China (No. 5442DZ180005) “Research and Application of Key Technologies for Medium and Long-Term Electric Quantity Security Check”.

Key words: margin of power quantity medium and long-term electric quantity security check future state model of power grid electric quantity adjustment
