To reduce the uncertainty of clean energy and improve the economic efficiency of microgrid scheduling
a scheduling model is established with the objective of minimizing microgrid operating costs and environmental management costs. Firstly
a new dynamic electricity price adjustment mechanism is proposed by integrating time-of-use electricity pricing and the absorption of clean energy
and then demand response is introduced to optimize the load comprehensively. Secondly
an improved grey wolf optimizer (IGWO) is adopted
which is based on the fusion of cosine law variation convergence factor
adaptive inertia weight
and Cauchy mutation. The IGWO is compared with other mature algorithms using typical test functions. Finally
simulation results show that using the IGWO algorithm to solve the price-based demand response model for wind and solar power integration can achieve optimal daily output and significantly reduce the total operating cost
thus verifying the feasibility and economic viability of the proposed research.
