A quantitative depreciation cost model is put forward for lithium batteries. A practical charging/discharging strategy is applied to battery management. The depth of discharge of the battery storage is scheduled more rationally. The proposed strategy improves the cost efficiency of lithium batteries in MGs.
Accordingly, the battery depreciation cost can be divided into two part: the fixed cost and the controllable cost. For the fixed part, the aging process is inevitable, and a battery has a finite calendar life. For example, once a battery is installed, it will be scrapped after certain years even if it has not been put into operation.
Some factors are independent of the dispatch strategy such as the ambient temperature and cumulative usage time. While some are controllable, such as the charging/discharging strategy and the DOD in a cycle. Accordingly, the battery depreciation cost can be divided into two part: the fixed cost and the controllable cost.
For further analysis of the economical impact of LB management method on MG, operational costs of the two methods are compared in Table 6. When considering battery depreciation cost under the proposed method, the average DOD of LB groups is 31.11%, lower than 80% under the traditional method.
Batteries are increasingly being used to reduce utility costs by: Peak shaving: discharging a battery to reduce the instantaneous peak demand . Load shifting: discharging a battery at a time of day when the utility rate is high and then charging battery during off-peak times when the rate is lower.
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
