The performance of the DG set is observed best when operated at full load or near full load (up to 70-80% load) condition. For this purpose a BESS is employed which ensures the load on the generator remains in between 80% to 100% of full load. Under light load condition (load less than 80%) the battery is being charged and in heavy load condition (load more than 100%) energy from battery is also utilized to feed extra power to the load. Along with load management, BESS provides the reactive power, harmonic and unbalanced load current compensation. The control of BESS is achieved using least mean square (LMS) based Adaline. The Adaline is used to extract the balance positive sequence real fundamental frequency component of load current. The switching of voltage source converter (VSC) working as BESS is achieved by forcing source currents to follow reference currents using hysteresis based PWM control. The scheme is simulated under MATLAB environment using SIMULINK and PSB block-sets. The modeling is performed for 3-phase 4-wire star connected synchronous generator, along with the 4-leg VSC working as BESS. The results verify the effectiveness of the Adaline based control of BESS to meet load compensation and optimal operation of DG set","PeriodicalId":191301,"journal":{"name":"2006 IEEE Power India Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114615354","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}

In this paper, we propose a short term load forecasting program for Reliance Energy Limited (REL) in Mumbai region. The method is based on a similar day approach. The development of forecast engine involves 4-steps. The first step involves discussion with domain experts (utility engineers) to extract and learn the rules regarding system behaviour. In the next step, these rules are refined by statistical analysis. A linear prediction model for each day of week is developed. The third step involves an adaptive implementation of the rules. The parameters of the linear model are learned from previous data by solving an optimization problem. Quadratic programming is used with redundancy factor 2. The final step involves fine-tuning of forecast by re-shaping the forecast as the reference day using fast Fourier transform, filtering and smoothening by 3-point moving average technique. Normalization is done using DC component of reference day. Since the parameters are learnt from past few weeks data, the seasonal variations due to change in season like winter, summer are better modeled. Detailed study of the results of the forecast program, the overall mean absolute percentage error (MAPE) of the forecasted data is 2.89 over an interval from Aug'04 to May'05 which is reasonable","PeriodicalId":191301,"journal":{"name":"2006 IEEE Power India Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128066294","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}

Chakrabarti","doi":"10.1109/POWERI.2006.1632552","DOIUrl":"https://doi.org/10.1109/POWERI.2006.1632552","url":null,"abstract":"The speed of wind at the different wind generator sites fluctuates due to weather variations over time. As a result, the wind generations may fluctuate over a wide range. The fluctuations and uncertainty are presently covered, in the New Zealand electricity market (NZEM), by the reserves originally offered for the protection of larger risk units in the system and frequency regulating reserve with no cost to the wind generators. In fact, smaller units benefit from the magnitude of reserves determined by the largest risk units. The frequency of outage of wind generators and variability of wind generation outputs is quite high compared to other smaller units and these frequently need a considerable amount of reserves to cover the generation fluctuations. The wind generators, therefore, \"free ride\" on other reserve providers adding cost to the system but not necessarily sharing them in an equitable manner. This issue has not been addressed so far. We develop a dispatch optimization model that recognizes the additional risk imposed by the wind generators. The model is based on DC-OPF, driven by generator risk contingencies, security margins at the load buses to cover the large variation of load, and security margins at the wind generator buses to account for the uncertainty of wind generations. The margins are maintained using reserves. The margin required at each wind generator bus is an input to the model and can be estimated statistically from its past performance. The main thrust of this paper is to examine the effect of security margin constraints at the wind generator buses and also at the load buses on the nodal spot prices. The paper demonstrates that the generation, and demand prices at a bus are different in the presence of binding security margin constraints. Generation prices at the wind generator buses get reduced in the presence of binding security margin constraints at these buses","PeriodicalId":191301,"journal":{"name":"2006 IEEE Power India Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122806372","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}
