IEC 61499 in Distributed Control of Weather Short-Term Load Forecasting Using Fuzzy Logic Algorithm
Abstract:
Distributed Control System (DCS) equipping the new design methodology comprises an open architecture for intelligent and agile control of distributed control systems by developing a novel international standard “IEC 61499” evolving the event driven functional modules distributed to field devices and interconnected among multiple controllers. It is investigated for predicting the short term power demand using weather and ambient conditions such as temperature, humidity, season, wind and precipitation. Forecasting algorithm simulated via Function Block Development Kit (FBDK) using Fuzzy Logic Controller (FLC). FLC is an advanced method for prediction and control of nonlinear system which is based on fuzzy logic concept comprising an algorithms formulated by linguistically expert rules. Precise mathematical model free system, robustness and flexibility in the event of parameter variations are the most advantages of FLC. In this approach three distributed weather stations are defined for estimating the power demand in a small area using IEC 61499 DCS standard and FLC as a prediction logic. IEC 61499 intensifies flexibility by capability in adaption and system reconfiguration in regard of environment changes, results on cost reduction and diminutions the industrial automation complexity. It increasingly enlarges the adaptability of proposed control system, enhances the system portability, interoperability and develops configurability. IEC 61499 facilitates world trade by swooping technical barriers to trade, eventuates the neoteric markets and economic growth and leads to a strong trend towards distributed automation systems.
