Optimal reactive power dispatch (ORPD) in a typical system is complicated multi-objective optimization problem. The proper modeling of the problem has significant impact on operation and control. In this paper, an Improved Heap-based optimizer (IHBO) proposed to improve performance recently published technique called (HBO). addition, two algorithms based original HBO IHBO are developed for solv...

This paper proposes a multi-objective load dispatch algorithm based on economic predictive control to solve the real-time problem of biomass heat and power cogeneration. According energy conservation law production process, optimization model for units is established. Then, concept utopia points introduced, comprehensive objective function defined coordinate conflict between performance polluta...

In the power system, economic dispatch is a popular and fundamental optimization problem. its classical form, this problem only considers thermal generators does not take into account network security constraints. However, other forms of problem, such as emission (EED), are becoming increasingly important due to emphasis on minimizing emissions for environmental purposes. The integration renewa...

Recent advancements in artificial intelligence especially in evolutionary algorithms have enabled much efficient way to solve the constrained optimization problems in various fields of engineering. In this paper we explain the development of the optimization techniques from single criterion to multi criterion. We also address the Combined Economic and Emissions Dispatch (CEED) problem in therma...

This paper proposes, an efficient variant of particle swarm optimization (PSO) to solve the multi-objective optimal reactive power flow (ORPF) based flexible AC transmission system (FACTS) using multi STATCOM Controllers by adjusting dynamically their parameters setting. Two objectives function are considered (power loss and voltage deviation) to validate the robustness of the proposed approach...

During the microgrid search process, optimal allocation and economic dispatch are very important and are interrelated, having interaction and mutual checks. In this paper, we adopt a bilevel planning method to search for the multi-objective optimal allocation of a microgrid, considering economic dispatch. The upper level is the optimal allocation, which aims at minimizing the daily fixed cost o...
