Battery energy storage systems (BESSs) are a key technology to accommodate the uncertainties of RESs and load demand. However, BESSs at an improper location size may result in no-reasonable investment costs even unsafe system operation. To realize economic reliable operation distribution network (DN), this paper establishes multi-objective optimization model for optimal locating sizing BESSs, w...

The optimal reactive power dispatch (ORPD) problem represents a fundamental concern in the efficient and reliable operation of systems, based on proper coordination numerous devices. Therefore, ORPD calculation is an elaborate nonlinear optimization that requires highly performing computational algorithms to identify solution. In this paper, potential metaheuristic methods explored for solving ...

In order to solve the problem of low voltage caused by unbalanced load in distribution network, a transformer loss intelligent prediction model under is proposed. Firstly, mathematical with an established. The zero-sequence impedance and neutral line current are calculated using Chaos Game Optimization algorithm (CGO), correctness proved actual data. Then, correlation among network input variab...
