The Several Stipulations of Generation Scheduling in Electricity Marke
In electricity market, generation scheduling of units must be arranged according to the relevant transaction scheduling and stipulations of generation dispatch, which mainly include determining the startup of bidding units, distributing the whole contract generation energy of a same generation company (power plant) to its relevant units, distributing marginal power to marginal bidding units and adjusting generation scheduling. Combing with the current stage of electricity market construction in china, this paper analynizes two stipulations to determine the startup of bidding units,which are by unit winning bidding energy and by unit contract energy. In order to coordinate the benefits between generators (the seller) and system operator (the buyer), two stipulations for distributing the whole contract generation energy of a same generation company (power plant) to its relevant units are put forward,which are by the proportion of unit available generation energy and by the proportion of unit winning bidding energy.This paper also discusses the distribution of marginal power to marginal bidding units and propose two basie distribution stipulations, which are the Proportion Method (for example, the proportion of unit bidding marginal power) and the Sequence Method (for example, unit sequence of submitting bid, unit generation efficiency and unit contribution to system security and stability). Finally, considering the composing characteristics of unit generation scheduling, this paper puts forward and analyzes two stipulations of adjustable and nonadjustable daily contract generation scheduling of bidding units.
