A Study on Operation Planning Models of Power Generation System Taking into Consideration the Uncertainty in Renewable Power Generation:
A Case Study on a Cost Reduction Measure by Introducing Battery Storage Systems
Summary
This report studied the generation cost impact of forecasting accuracy improvement and battery storage system in power systems with large-scale renewable integration using power system operation models.
The model results show that the forecasting accuracy improvement and battery storage system could make lower the on-line capacity of partial-load oil-fired and gas-fired power generation units and make the base load power generation units more utilized. This has negative impacts on the yearly power generation cost as well. These results imply that, studies on controlling a variety of flexibility resources in an integrated way, e.g. conventional power generation unit, battery storage system, demand response and hydrogen, are needed combined with renewable power forecasting from a viewpoint of power generation cost reduction.
