Mathematic models for minimum cost in security management of power market

Abstract

基于归一化能量裕度对电力系统可控参数的二阶灵敏度算法,提出了电力系统以经济代价最小为目标函数,以动态安全为约束条件的数学规划模型。该模型同时适用于单一类型和合同与非合同混合类型两种市场模型,既可用于市场交易管理又可用于在线安全控制。最后通过新英格兰10机典型电力系统上的算例说明了它在电力市场安全管理中的应用方法。 Based on an approach of the second order sensitivity of normalized transient energy margin, this paper proposes mathematic models for minimum cost in security management of system in environments of power market under transient stability constraints of power system. The models are suitable for power markets of both pool type and coexistence of contract and non-contract trades. The proposed models bring together both technical and economic considerations and the application of the models is illustrated using the 10-generator New England test system.
