Robust Design Optimization of Electromagnetic Actuators for Renewable Energy Systems Considering the Manufacturing Cost

Abstract

Power transmission and protection of power electronics–electromagnetic actuators are crucial parts in renewable energy systems (energy management of photovoltaic, wind power, hybrid and electric vehicles). Consistency optimization of electromagnetic actuators has attracted extensive attention from corporations in competitive markets. Robust design has been widely applied for reducing the influence of uncertainties in the manufacturing process to improve the consistency of product quality. However, the cost factors of the actual manufacturing process are not fully considered in state-of-art methods. Although the consistency has been improved, the optimization scheme may not be optimal from the perspective of engineering applications, because unnecessary cost increments may be produced. In this paper, an application-oriented robust design method for consistency optimization is proposed. The impact of tolerance values on quality loss and manufacturing cost can be considered simultaneously to guide the tolerance optimization process. Thus, the optimal solution of total loss is obtained by optimizing the quality fluctuation to the design objective with the minimum increment of manufacturing cost. An example of the consistency optimization of an electromagnetic actuator used in the photovoltaic system is presented to illustrate the procedure and verify the effectiveness of the proposed method.

Development of Sustainable Energy Use with Attention to Fruitful Policy

“…[93]. The actions such as Tariff policy amendments [94], encouraging investors to come to energy markets [95], full support of the equipment failure [96], forecasting natural disasters to prevent damages, and tackle potential hazards in relation with energy [97], issued the standardisation of renewable energy projects policy (testing, standardisation, and certification) [98], action plans for standards (testing and certification of performance) for renewable energy [99], improvement of manufactured components of the energy systems [100], improvement and co-optimisation of the infrastructure of energy systems [101], developing markets of renewable energy [102], finding main barriers of energy systems [103], review mechanism of energy efficiency policies especially for buildings [104], critical revisions energy efficiency policies [105], reduce the subsidies and invest in Research & Development Funding (R&D) lagging [106], increasing manufacturing storage system affordable to reduce the cost of renewables [107], and renewable energy technologies development [108], can be efficient as proper policy and regulatory framework initiatives by governments in sustainable energy use development.…”

A novel hybrid cuckoo search algorithm for optimization of a line-start PM synchronous motor

“…Heuristic (probabilistic) optimization algorithms have been applied for several years now in order to solve different optimization problems [1][2][3]. Such algorithms are very often used to solve optimal design problems of electromagnetic devices, such as transformers, motors, generators and actuators [4][5][6][7][8]. The optimization procedure often cooperates with a mathematical model of the devices studied, elaborated by means of finite element analysis (FEA).…”

A Novel Fault Diagnosis Approach for the Manufacturing Processes of Permanent Magnet Actuators for Renewable Energy Systems

“…The manufacturing process parameters are used to characterize the process quality. The complexity of MMPs and an abnormal variation in the MP parameters inevitably cause unit-to-unit variability, resulting in a poor qualified rate and poor reliability in the batch production [16][17][18]. Therefore, it is imperative to conduct an effective fault diagnosis of MPs and resolve the abnormal variation sources.…”
