Published: Jan. 1, 2025

ABSTRACT This paper presents the allocation and planning of renewable distributed generations such as wind turbines photovoltaic systems, non‐renewable generators fuel cells in microgrids that incorporate electric vehicle parking lots while considering financial, operational voltage stability goals. The proposal is modelled form a bi‐objective optimisation problem. One objective functions minimises generators’ cost microgrid's cost, other function maximises index. problem solved, satisfying technical constraints power flow, network operational, limits incorporating models vehicles resources. ε‐constraint‐based Pareto solution used to determine single‐objective formulation next step. Then, fuzzy decision‐making tool derives compromise solution. Finally, Crow Search algorithm finds trustable optimal performance validated on standard microgrid using numerical analyses shows can effectively economic conditions.

This study presents an optimal approach to integrate flexible-renewable virtual power plants (VPPs) into the operation of active distribution networks (ADNs) with multi-criteria objectives for day-ahead energy and reserve markets. The level interaction VPPs is determined through a risk model. proposed framework adopts bi-level structure. In upper-level model, Pareto optimization strategy, based on weighted sum method, utilized minimize AND's predicted operating costs voltage deviation. network's AC flow (AC-OPF) equations serve as constraints this level. lower-level model intends maximize VPPs' expected profits while incorporating conditional value-at-risk address their participation in aforementioned Additionally, constrained by operational characteristics VPPs. Stochastic programming applied capture uncertainties associated renewable sources, market prices, system loads. problem transformed single-level applying Karush–Kuhn–Tucker conditions. A hybrid solver, combining teaching–learning-based sine–cosine algorithm, employed acquire reliable near-optimal solution. Finally, scheduling ADNs can be replace conventional studies determining numerical findings indicate that improve economic efficiency resources responsive loads when VPP framework.
