A novel strategy for economic management of distribution networks in bilateral energy markets contemplating electrical storage, thermal generations and distributed generations private behavior

This study is presented a novel policy for management of hour-ahead active and reactive market considering privatization of Distributed generations (DG). The studied network in this paper is included Double Feed Induction Generator (DFIG) wind turbines, battery energy storage systems and thermal units. The economic environment in this study is a forward day-ahead bilateral market. These privately owned wind turbine units use batter storage systems (BES) owned by a distribution networks, which forms an integrated distributed system with storage (DFIG-BES) on some buses. In order to maximizing benefit of the distribution networks the standard IEEE 33 bus system is utilized. Determining the contribution of the BESs, thermal units, DFIG-BESs and DFIGs, their generations, power exchange with the substation, voltage level of each bus and benefit of the distribution network can be attained by implementing and AC power flow in GAMS software. Economic competition and market model is stand on a forward day-ahead bilateral planning and distribution networks that have contract with suppliers. For solving the problem and optimization, a mixed integer nonlinear programing method is employed. The results confirm that using the proper strategy in determining the portion of active and reactive power of the units owned or contracted by the distribution company on an hourly basis can significantly improve the voltage level, reduce losses and line congestion, and ultimately leads to increase of the profit of the distribution company.
