%0 Journal Article %T On the properties of nodal price response matrix in electricity markets %A Vadim Borokhov %J Mathematics %D 2014 %I arXiv %R 10.1109/TPWRS.2014.2376494 %X We establish sufficient conditions for nodal price response matrix in electric power system to be symmetric and negative (semi-)definite. The results are applicable for electricity markets with nonlinear and intertemporal constraints. %U http://arxiv.org/abs/1404.3678v2
