| 摘要 | ln an interconnected power system, overdrawal of power from one area by a neighbouring area causes a frequency clip in the system. This paper presents a real-time pricing scheme that is effective in controlling the frequency and tie-line power excursions. The proposed scheme is adaptive and is updated every sampling period by deriving its input from the area control error (ACE). The pricing scheme takes into account the system dynamics and gives the importing area a signal in terms of increased price for any increment in the drawal from its scheduled value. The increase in price can be viewed as a penalty that discourages any deviation from the scheduled power flow and thereby ensures grid discipline. Two cases have been considered: demand pricing, in which the importing area reduces its demand in response to the price and generation pricing, where the exporting area adjusts its generation to a change in demand by directly responding to the price signal. Simulation studies considering a two-area reheat thermal system reveal that both pricing schemes yield satisfactory system dynamic responses. |
