At 30-60°C temperature, the mushrooms were dried in a natural convective dryer and after certain time intervals the enzymatic activity and the moisture content were measured. Genetic Algorithm (GA) method was used for the simulation and optimization process and the experimental data were used to fit the models. The results indicated that, after 350 min of the drying process the mushrooms were dried. Among the utilized models the best result was presented by the proposed model. The result showed that around 50°C and between 300-400 min of mushroom drying process, the specific activity was found 5.12±0.05 SKB/mg and 12.5±0.05% (wet basis) of reaming moisture content with minimum energy consumption.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114243899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first stage is a Modified Incremental Conductance Algorithm (MICA), used to generate the maximum power reference current. And the second stage utilizes Model Predictive Control (MPC) for controlling the PV module and achieves the maximum power. The proposed algorithm has the ability to track the maximum power under sever environmental conditions and reaches to steady state at a very small time. Ultra-Step-Up Boost Converter (USUBC) is proposed in this paper for Photovoltaic (PV) application.

The unscheduled supply interruption is triggered by several reasons which draw attention to the connection of micro generation especially to Low Voltage (LV) network. Malaysia requires an extensive research in order to implement a new and feasible grid named MG. According to the IEEE 1547.4, the vital issue in the MG is active power. To investigate the MG operation, the MG modelling was established to cope with this problem. These model tested five cases of transition modes between grid and MG based on IEEE Standard 1547.4 and TNB Guidelines were simulated using Matlab/Simulink. Each case was analysed based on the switching time on power systems and fault insertion to show the transition in terms of active power between both power systems and operation modes.","PeriodicalId":444960,"journal":{"name":"2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128229468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on multi-objective optimal scheduling of a DC micro-grid consisted of PV system and EV charging station is proposed in this paper. Based on the structure of the DC micro-grid and function of each component, mathematical model of the multi-objective optimization for scheduling, which takes the cost of electricity purchasing and energy circulation of storage batteries as objective functions, is built and then solved with NSGA-II. Constraints including EVs' charging time, the range of the charging/discharging power and SOC (state of charge) of the storage batteries, power supply rate of the distribution network and system power balance are considered in this model. A certain case is studied and verifies the model's rationality.
