Abstract
At the background of direct electricity purchasing by big customers at present, it is required to rigidly complete contract electricity quantity, while due to changes of some factors such as load deviation and fault overhaul, contract electricity quantity may not be accurately completed. With transaction components become more and more complicated, higher requirement is put forward upon equality of complete schedule of different component of electricity quantity. Therefore, power grid corporations are eager to need a kind of high efficient and accurate intraday generation scheduling model and method which can realize rolling adjustment on unit output and complete the target of keeping schedule equality of the contract electricity quantity on the premise of ensuring safe operation of the power grid. Thus, this paper presents intraday generation scheduling model and method adaptive to multi-component direct transaction in the electricity market which can real-timely track complete schedule of contract electricity quantity. By using rolling modeling method, the model and method sets different quadratic penalty coefficients for different transaction components so as to realize accurate and balanced control for complete schedule of contract electricity quantity. Testing result of one provincial power grid also indicates the proposed model and method can greatly improve completion rate and equality of electricity quantity.关键词
