Optimal Reconfiguration and Distributed Generation placement in Baghdad Distribution Sector

Abstract

The power losses in distribution system are high, which form 70-80% of total transmission and distribution losses. High losses have severe impact on stability, reliability as well as economy. Therefore, minimization of these losses is very necessary. In this paper proposed various schemes to reduce the active power losses in distribution network, given as:-Optimum reconfiguration network,-Optimum Distributed Generation (DG) placement and-Optimum reconfiguration with optimum (DG) placement. Using Cymdist software to implement the optimal reconfiguration algorithm and proposed Genetic Algorithm (GA) to find the size and location, which programmed under MATLAB software package. Whereon the proposed methodology (GA) simplifies the problem by dividing it in two phases, namely Placement Planning Model (PPM) and Size Planning Model (SPM) thereby reducing the search space. It was the integration of the two methods were used after each method individually to obtain minimum real power losses with better bus voltage (better efficiency for network).To verify the proposed algorithms, IEEE 33-bus system and aljihad neighborhood distribution system (Baghdad distribution sector) are tested. The simulation results are compared with proposed works in literature.

A hybrid algorithm for voltage stability enhancement of distribution systems

“…Then, the D-STATCOM is placed at 30 th bus as the optimal location (case 2), the total power loss has been reduced to 143.6 kW and the minimum VSI is enhanced to 0.7355 p.u, while the results obtained in [18] are 144.38 kW and 0.7228 p.u respectively. In this case, the authors have taken the line data of RDS presented in [36], [37] which differs from the line data considered in this paper but the same line data considered in [27] in case placement D-STATCOM. In case 3, one DG (type one) is optimally placed in the 6 th , bus with 2720 kW as an optimal size.…”

Impact of Distributed Generation on a Distribution Network Voltage Sags in Baghdad City

“…Application of DG in the distribution network is expected to mitigation the voltage sag. DG is a compact electrical power source that is connected directly to the distribution network or at a location closer to customers [3,4].…”

Enhancement of an Iraqi Radial Distribution System Performance Using Multi-Object Particle Swarm Optimization

“…Several studies have been presented under the name of met heuristic techniques such as ",Whale Optimization Algorithm(WOA) [8], Improve Differential Search Algorithm (IDEA) [9], Genetic Algorithm ( GA) [ 10],A combination of Genetic Algorithm and Particle Swarm Optimization ( GA and PSO) [11]], Particle Swarm Optimization (PSO) [12], Grey Wolf Optimization Algorithm (GWOA) [13], Harmony Search Algorithm (HSA) [14],Gravitational Search Algorithm (GSA ) [15] and Slap Swarm Algorithm (SSA) [16]" to find the optimal site problem of DG and D-STATCOM in power systems. A lot of studies mentioned above have been carried out to locate the optimal location and size problems of DG and D-STATCOM devices separately or simultaneously but did not add multiple DGs and D-STATCOMs in the real systems [12,17].…”
