In order to solve the problem that the source-load interaction mechanism is unclear when short-process steel enterprises participate in peak regulation of power system with high proportion of renewable energy
resulting in the limited effect of system peak regulation
an optimal control method for short-process steel enterprises to participate in power system peak regulation is proposed. Firstly
the peak regulation architecture of the renewable energy system integrating the production load of short-process steel enterprises is designed
and a hierarchical response model is constructed according to the load regulation characteristics. Secondly
based on the non-cooperative game process of grid demand release
enterprise response solution and aggregator information interaction
the dual signal response mechanism of electricity price and incentive is formulated
taking into account power grid peak regulation demand and enterprise production electricity consumption in the high proportion of renewable energy power system. Finally
a two-layer economic scheduling model of source and load is constructed
and the model is solved through hierarchical iterative and the balance of source and load interests is achieved. The simulation results show that the proposed method can reduce the peak-to-valley difference of load by 2.74%
increase the renewable energy accommodation of the power grid by 5.53%
and reduce the comprehensive electricity cost of enterprises by 17.72%
which significantly improves the response enthusiasm of enterprises and improves the peak regulation effect of the power grid.
