Abstract

The invention discloses a wide area source-load day-ahead active power optimization control method. The method includes reading related data of various power supplies, centralized industrial loads anddistributed civilian loads; performing packet aggregation processing on the distributed civilian loads; calculating aggregation regulation performance parameters of aggregation loads of each group; constructing and solving a wide area source-load day-ahead active power optimization model to obtain a day-ahead active power plan of the various power supplies, the centralized industrial loads and aggregated civilian loads; and distributing the day-ahead active power plan of each distributed loads in the aggregated civilian loads. Adjustment characteristics of multiform elastic loads can be fullyconsidered by the method, and thus, the characteristic analysis problem of massive wide area distributed loads can be solved by using an aggregated manner, coordinated optimization control of wide area multiform elastic loads, conventional power supplies and wind power can be realized, and consumptive capacity of power grids on wind power can be enhanced.

Description

technical field [0001] The invention belongs to the field of active power optimization control of new energy power systems, and in particular relates to a wide-area source-load day-ahead active power optimization control method. Background technique [0002] With the rapid growth of wind power installed capacity in large-scale 10-million-kilowatt wind power bases, the proportion of wind power in the system has increased. The randomness and volatility of wind power increase the pressure on the power grid for peak regulation, and it is impossible to fully absorb wind power only by relying on the output of conventional units. On the load side, centralized elastic loads (such as high energy loads) and distributed elastic loads (such as heat storage electric boilers, etc.) both show good regulation characteristics, can participate in grid dispatching, and promote wind power consumption. However, the characteristics of elastic load regulation are complex, and the distributed elas...
