Introduction

The evolution of power systems has been fundamentally shaped by technological advancements and the increasing integration of renewable energy resources [1]. Traditional power grids were primarily designed for centralized generation and unidirectional energy flow, with limited capacity to adapt to dynamic load patterns or incorporate distributed generation. The rise of renewable energy sources such as solar photovoltaic and wind energy has introduced significant variability and intermittency, challenging conventional grid operations [2]. The integration of distributed energy resources (DERs), coupled with rising consumer demand for reliable and cost-efficient electricity, necessitates the development of intelligent energy management systems capable of real-time monitoring, forecasting, and control [3]. AI-driven approaches offer the capability to handle complex, high-dimensional data from heterogeneous sources, enabling predictive analytics, optimization, and automated decision-making that enhance grid performance and resilience [4, 5].

Load forecasting constitutes a cornerstone of modern energy management, providing critical information for operational planning, demand response, and energy dispatch [6]. Short-term, medium-term, and long-term load predictions allow operators to anticipate fluctuations in consumption and generation, improving resource allocation and minimizing operational inefficiencies [7]. Traditional statistical methods, including autoregressive models, exponential smoothing, and ARIMA techniques, offer foundational approaches to capture temporal patterns [8]. However, the emergence of machine learning and deep learning frameworks has dramatically improved forecast accuracy by capturing nonlinear relationships, temporal dependencies, and interactions among multiple variables [9]. Hybrid models, combining classical statistical techniques with AI-based predictive models, further enhance robustness and adaptability, particularly under highly stochastic and uncertain conditions imposed by renewable integration [10].

Optimization of smart grid operations extends beyond accurate forecasting to include dynamic energy management, peak load reduction, and reliability enhancement [11]. Reinforcement learning, metaheuristic algorithms such as genetic algorithms, particle swarm optimization, and ant colony optimization, and multi-agent systems provide adaptive strategies for coordinating distributed energy resources, energy storage, and flexible loads [12]. Predictive control techniques enable proactive decision-making that considers both short-term operational objectives and long-term performance metrics [13]. The integration of these intelligent optimization strategies ensures efficient resource utilization, reduces curtailment of renewable generation, and mitigates the impact of sudden demand surges or generation deficits [14]. These approaches also facilitate demand response programs, enabling automated, real-time load adjustments based on predictive insights and market conditions [15].
