Abstract

Utilizing electricity from renewables requires significant back-up generating capacity for the reason that solar and wind energy outputs could vary throughout the days, seasons and affected by weather conditions. This paper examines the impact of storage technologies integration to the power system of Kazakhstan based on optimization model. System components involve nodes and regions allowing the model to interact among these division sets trough transmission lines. Using the data elaborated by the Kazakhstani Electricity Grid Operating Company (KEGOC) the model allows to observe the nodal level interconnection of the spatial characteristics of the power system till 2050. Model results indicate that storage facilities could improve the reliability of power system and reduce electricity costs by storing electricity at the low electricity demand hours and low prices for utilizing stored electricity at peak demand hours. The proposed model determines the optimal way of implementation of energy storage technologies and renewable energy sources, their capacity and amount of investment. With the assumption that the generation from conventional power plants is fixed on the level of 2015 we have tested various levels of implementation of storage technologies. The resulting optimal ratio of installed capacity of storage to installed capacity of renewables is between 10-15%.
