Analysis of cost value mechanism for backup auxiliary services in power systems considering the participation of new energy
To address the issue of market mechanism for new energy participation in auxiliary services,a cost value mechanism for back-up auxiliary services that takes into account new energy participation was proposed.Adopting a cost value method for backup services based on cost and benefit evaluation,combined with the situation of China's primary electricity market,a pricing model combining the opportunity cost,system value of lost load,and system reliability indicators of new energy to provide rotating backup services was pro-posed.A supply cost model represented by opportunity cost was established,and benefits were calculated based on the value of lost load(VOLL)of service benefits based on consumer surplus theory.And the compensation price for providing auxiliary services for new ener-gy was comprehensively and reasonably determined using the reliability index loss of load probability(LOLP)as the weight.Finally,an example analysis was used to illustrate the nonlinear relationship between reserve expected value and load demand,in order to further optimize the relationship between reserve auxiliary services and load in the power grid.
