The Probabilistic Power System Production Simulation Based on Chronological Load Curve

A new model and the relevant algorithm for probebilistic power system production simulation bssed on chronological load curve are presented.The model is based on the combination of Available Capacity Probability Density Function (ACPDF)and chrono logical load curve,so that the chronological constaints can be easily taken into account,and the calculation of hydro system optimizing can be done more effectively.In out algorithm,all thermal unit are loaded on by one in merit order and the expected energy of each unit is the increament of system generating capacity affer putting it into system. During calculating,only ACPDF needs convolution and deconvolution whereas the load curve keeps constant,thus,the numerical stability of the algorithm is better than that of Others.The model and algorithm have been applied into IEEE-RTS and Northeast China power system and the satisfactory results have been achieved.
