Market mechanism design for grid⁃forming power equipment participating in inertia and electric energy markets
In order to deal with the shortage problem of inertia and primary frequency response in new power system,a new market mechanism of grid⁃forming power equipment participating in inertia and electric energy markets is proposed,which motivates each power equipment to provide inertia and primary frequency response. The virtual inertia and droop factor provision capabilities of grid⁃forming inverter and grid⁃following inverter under different control strategies are analyzed,the impact of response delay of each po-wer equipment on system frequency is comprehensively considered,a three⁃stage system dynamic frequency response model is constructed,and the frequency security constraints are derived. On this basis,an inertia⁃electric energy joint market clearing model considering frequency security constraints is constructed,and the inertia and droop factor provided by each power equipment are priced. The example of IEEE 30-bus system based on historical data of California Independent System Operator shows that the proposed mechanism can effectively coordinate electric energy,inertia and primary frequency response resource,and ensure economic returns of each power equipment through rational pricing.
