An Overview of Integration Costs of Variable Renewables in the Power
An Overview of Integration Costs of Variable Renewables in the Power Sector 4 Ueckerdt et al. (2013) introduced the system LCOE metric, which is the sum of the plant''s marginal generation costs and marginal integration costs. The authors divided the costs of the system into VRE generation cost and residual costs.

The cost of photovoltaics: Re-evaluating grid parity for PV systems
However, the traditional LCOE only considers the generation costs within the power plants, such as the initial cost and operation and maintenance (O&M) costs, neglecting many cost components that are specific for PV, resulting in an overly optimistic cost scenario [[18], [19], [20]]. Compared with fossil fuel power generation, PV power generation is variable,

The economics of concentrating solar power (CSP): Assessing cost
The trade-off between solar multiple and thermal storage capacity is crucial in achieving cost-effective power generation in CSP plants. The solar multiple expresses the ratio between the thermal energy captured by the solar field and that required to operate the power cycle at a nominal load [69]. Therefore, a solar multiple higher than one
