While diesel generator sets have proven to be a reliable and accessible technology, their downside involves the expense and environmentally emissions linked to diesel fuel consumption. In response diesel generation alternatives are becoming both available and cost competitive, specifically via the integration of renewable energy technology (RET). Hybrid power systems (HPS), those adopting both diesel and RET are increasingly employed to reduce both cost and environmental emissions. As renewable penetration increases within HPS a potential conflict arises, with diesel generation unable to lower output below minimum load set points. These load set points are predetermined to ensure engine efficiency and preserve engine condition. Under medium to high renewable penetration, diesel load set points compete with renewable generation to produce surplus energy. This surplus energy must be absorbed by the system, and while various ancillary technologies, such as demand management, energy storage and dump loads can perform this role, such technologies add expense and complexity. This paper investigates low load diesel (LLD) as one solution to minimising surplus generation within HPS. HPS modelling is used to explore removal of energy storage systems (ESS’s) under LLD application. Model validation, undertaken against both kW and MW scale operational diesel generator data sets is referenced to support the findings of both models. Results show LLD to reduce both system establishment and operational costs for high RET penetration HPS.
