【摘要】：電網(wǎng)動態(tài)最優(yōu)潮流是一個(gè)全天24個(gè)時(shí)間斷面耦合的最優(yōu)潮流問題,需要考慮常規(guī)機(jī)組爬坡率約束和分布式儲能裝置能量約束。具有二階收斂特性的內(nèi)點(diǎn)法可以對其進(jìn)行快速求解,但無法保證解的全局最優(yōu)性。采用對偶半定規(guī)劃法求解該問題,對孤島運(yùn)行的微電網(wǎng)動態(tài)最優(yōu)潮流原始模型及向?qū)ε及攵ㄒ?guī)劃模型的轉(zhuǎn)換做了詳細(xì)的介紹,并給出了嚴(yán)格的全局最優(yōu)性判據(jù)。同時(shí)將儲能裝置的強(qiáng)非線性模型等價(jià)地變換成線性模型,并給出了相應(yīng)的證明。某實(shí)際微電網(wǎng)和IEEE 30節(jié)點(diǎn)系統(tǒng)的測試結(jié)果表明,對偶半定規(guī)劃法可高效求解動態(tài)最優(yōu)潮流問題,其解可保證全局最優(yōu)性。
[Abstract]:The dynamic optimal power flow is an optimal power flow problem which is coupled with 24 time sections throughout the day. It is necessary to consider the slope climbing rate constraints of conventional units and the energy constraints of distributed energy storage devices. The interior point method with second order convergence can be solved quickly, but it can not guarantee the global optimality of the solution. The dual semidefinite programming method is used to solve the problem. The original model of dynamic optimal power flow and the transformation to dual semidefinite programming model are introduced in detail, and the strict global optimality criterion is given. At the same time, the strong nonlinear model of energy storage device is transformed into a linear model on an equivalent basis, and the corresponding proof is given. The test results of a practical micro-grid and IEEE 30-bus system show that the dual semidefinite programming method can efficiently solve the dynamic optimal power flow problem, and its solution can guarantee the global optimality.
