| Abstract | The future electric grid is likely to see many changes, mostly at the distribution side, which includes high penetration of distributed generation (DG), dynamically changing loads like electric vehicle charging loads, increased loads, etc. Most of the distribution systems these days lack sufficient control and monitoring facility to deal with such changes. Distribution network reconfiguration is a commonly used technique which provides an efficient, fast and economic mode of control of load flow. However, with the changing load and generation, the network topology reconfigured by this method may not always be optimal. The study has been divided into three objectives. The objective-1 is dedicating to establish a well-designed algorithm for network reconfiguration implementing NSPSO and validate its output. Objective-2 investigates into the effectiveness periodical network reconfiguration as compared to without any or just one reconfiguration based on their performance with respect to changing load and generation. Likewise, objective-3 investigates the effectiveness of coordination of network reconfiguration with reactive power dispatch from DGs with the aim to minimize the loss of active power output from DGs. Here, four cases are considered for performance comparison. Case-1 considers no reconfiguration or reactive power support from DG, case-2 considers reactive power support from DGs without reconfiguration, case-3 in corporates reconfiguration without reactive power support from DGs and case-4 assumes reactive power support from DGs with network reconfiguration. It also draws a performance comparison for different cases with combination of with or without reactive power dispatch from DGs and with or without network reconfiguration. |
