基于Lyapunov指数的电力系统短期负荷预测

Power System Short-term Load Forecasting based on Lyapunov Index

短期负荷预测为发电计划程序提供数据,是电力系统经济运行和安全控制的基础。介绍Lyapunov指数预测法的步骤,以东北电网1994年的负荷数据为例,探讨Lyapunov指数预测法的预测准确性,确定其误差符合电力负荷预测的要求,适于在电力系统短期负荷预测中广泛应用。

Short-term load forecasting provides data for power planning program. It is the foundation of economic operation and safety control of power system. This article describes the Lyapunov index forecast procedures. Taking the load data of Northeast Power Grid in 1994 as an example, the author checks the prediction accuracy of Lyapunov prediction method, showing that the error is within the power load forecasting requirements, and the method is suitable for extensive application in short-term load forecast in electric power system.
