EVALUATION OF EFFICIENCY OF USE OF ENERGY STORAGE SYSTEM IN ELECTRIC NETWORKS

Ways for the use of energy storage systems (ESS) in electrical networks are considered. The formalization general approach to solving problems efficient ESS is performed. article shows mathematical models evaluating effectiveness using and determination optimal configuration, including regulation modes electric networks. operation network with an connected group four standard IEEE 33-node 12.6 kV was used as a base model. A new target function has been proposed. This based on benefit installing consists annual cost buying / selling electricity by ESS, reducing active losses grid due corresponding investment costs. results optimization calculations proposed objective given. comparative analysis obtained estimation components under condition elimination deviations voltage levels separate nodes from normalized values References 33, figures 2, tables 2.
