The objective of this work is to obtain an appropriate generation schedule satisfying system constraints and unit operation constraints with effective spinning reserve without tie-line congestion problem. The hybrid mixed integer programming process includes mixed-integer linear programming and quadratic programming (MILP-QP) is used to find the feasible solutions with total cost minimization while satisfying all important constraints. MILP is used to find generation schedule whereas QP is used to perform economic dispatch. It is tested on a ten unit system in three cases with 1, 2 and 3 areas linking with tie lines under DGS (Decentralized Generation Scheduling) and CGS (Centralized Generation Scheduling). Numerical results show that MILP-QP with DC line flow and virtual load constraints could provide feasible solutions effectively. Without virtual load constraints, line congestions may occur due to unforeseen higher load demand in next few minutes.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"25 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120821290","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}

There are plenty of researchers who proposed methods to reduce power losses. To achieve more efficient use of energy sources. This paper represents a method of finding the optimal position of a wayside energy storage attached to a passenger station platform. The test starts with collecting the regenerative braking energy acquired from an arriving train to the stopping platform. This braking energy is useful to accelerate a departing train apart from the station. If there is no train standing on the departing platform, the braking energy is rerouted and therefore is stored in a stationary energy storage device. The reuse of braking energy is free. However, it may be wasteful due to a relatively long leading current-carrying cables. To minimize the wasteful energy of the feeding cables, position of the stationary energy storage can be allocated to an appropriate location in such a way that the overall feeder losses are minimized.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121221446","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}

When it is used in the long time, the efficiency is reduced. A problem is occurred because it is covered by sulfate on the surface of the lead plate electrode. This cause on current supply efficiency of the battery is decreased because resistance increases. This research presents the way to solve the problem. The sulfate must remove out of surface of the lead plate electrode. The high frequency stimulation signal generation is applied. A car battery 12 V 75 AH is experimentally tested. CCA meter model of AE300 is as a tool for efficiency observing. The high-frequency stimulation circuit at 64.7 kHz is designed. The experiments were done by applying DC voltage as a ripple high-frequency onto the electrode plates with different time intervals. The result shows that Cold Cranking Amp (CCA) value of the battery is increased. Therefore, it can be summarized that 64.7 kHz high frequency stimulation can increase the efficiency of battery.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125926400","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}

A train movement is based on a sequence of four operation modes: i) accelerating mode, ii) constant speed or cruising mode, iii) coasting mode and iv) braking mode. The optimization problem in which the train speed profile is optimized by controlling of three parameters: i) acceleration rate ii) deceleration rate and iii) location of coasting point. By using Quadratic Search Method (QDS) which is a mathematical method to calculate the optimal location of the coasting point, with the goal of using the minimum energy consumption and no effects with the train movement and the operating time of the train services. The case study applied in this paper is a mass rapid transit system which travels between two passenger stations with a service distance of 1 km and a maximum speed of 45 km/h. The results showed that the longer distance of the coasting mode the less power consumption in the cruising mode and the less power from the brake mode. On the other hand, the short distance of the coasting mode the more power in cruising mode and the more power from the brake mode. It is found that the optimal location of the coasting point obtained by QDS is considerably capable to reduce the overall energy consumption by 3.8%.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129913631","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}
