Optimal Capacity Allocation Model for Wind Power-CSP-Biomass Hybrid Power Station Considering Operational Reliability

Wind power-concentrating solar power (CSP)-biomass hybrid power generation contributes not only to the overall operation income but also the scheduling of the system. The capacity allocation between the modules is also important to the economy of the entire hybrid power station. This is why we proposes an optimal capacity allocation and dispatch model for the wind power-CSP-biomass hybrid power which takes the output deviation penalty of the hybrid power station, wind and solar curtailment penalty, and the minimum operation cost for the capacity allocation of the hybrid power station as the objective function. In addition, considering the output uncertainty of the CSP and wind farms, this paper uses reliability indicators to put the constraints on the operation of hybrid power stations in an attempt to reduce the load shedding, wind and solar curtailment of the system, and meet the demands of load flexibility. Finally, the proposed model and method were validated through case analysis to reduce operating costs by 40%..
