SMELL AGENT OPTIMIZATION FRAMEWORK FOR PHOTOVOLTAIC–WIND TURBINE–BATTERY ENERGY STORAGE SYSTEM INTEGRATION IN SMART DISTRIBUTION NETWORKS CONSIDERING LOAD MODELS AND RELIABILITY INDICES
DESIGN DETAILS
The rapid pe*******on of renewable energy resources and battery energy storage systems (BESS) in active distribution networks introduces significant operational challenges related to voltage stability, power loss minimization, and reliability enhancement. This paper presents a comprehensive optimization framework for the simultaneous allocation and optimal sizing of photovoltaic (PV) units, wind turbines (WT), and BESS using the Smell Agent Optimization (SAO) algorithm.
The proposed SAO-based approach effectively minimizes total active power loss and voltage deviation while satisfying network operational constraints. A 24-hour time-series analysis is incorporated using realistic solar irradiance and wind speed data to accurately model renewable generation variability.
Furthermore, the framework evaluates system performance under multiple load models, including constant power (CP), constant current (CI), constant impedance (CZ), and ZIP load models, ensuring robustness under diverse operating conditions. Reliability assessment is integrated through standard indices such as SAIDI, SAIFI, EENS, AENS, ASAI, ASUI, and CAIDI.
The proposed methodology is validated on the IEEE 33-bus radial distribution system considering six installation scenarios: PV, WT, BESS, PV–BESS, WT–BESS, and PV–WT–BESS. Simulation results demonstrate significant reductions in power losses, improved voltage profiles, and enhanced system reliability. Notably, the coordinated integration of PV–WT–BESS provides the best overall system performance.
The Smell Agent Optimization algorithm employs sniffing, trailing, and random search mechanisms to achieve an effective balance between exploration and exploitation, enabling efficient identification of optimal distributed energy resource configurations. The algorithm exhibits stable convergence characteristics, strong global search capability, and robustness under varying operating conditions, confirming its effectiveness for multi-source distributed energy planning in modern smart distribution networks.
MULTI-OBJECTIVE FUCNTION
The objective function,F(k)=min{w_1 f_1 (k)+w_2 f_2 (k)}
