  Grid Operation Short Term Load Forecast Better Start With PART-1 Preface: There are some industries that produce intermediates only.  Their product is not for consumers but it is input to other industries producing final product for consumers. In the chemical sector, some industry   produce intermediates that is input for other industries like pharmaceutical, colors, detergents, cosmetics, etc. Similarly various industries produce different machine parts that are used in industries producing machines for consumers. The objective of this write up is similar. It was observed that many academic and field experts have developed efficient models for Short Term Load Forecasting using different logics and techniques. But when applied to field data, in many cases, the results were not as accurate and consistence as expected. Reason may be discrepancy in data itself and result was GIGO. Here I have some useful information in the matter as a practicing engineer havin...

  Grid Operation Part 5 Operation Planning and Control Better Start With PART-1 Power system operation planning is done on the previous day for implementing it on the next day. All required data like forecasted load, generation availability, network status, etc are collected along with schedule changes. Operation planning, monitoring and control is a continuous task because operation planning has to be modified in real-time to accommodate unexpected changes in generation, demand, network, etc. Power system operation planning and control is based on three fundamental criteria 1.       1 .      System security. System security remains a top priority while system operation planning, monitoring, and control. Therefore any occurrences that jeopardize system security are set right immediately by suitable measures. Practically 100% security cannot be guaranteed but the security level has to be enough that changes of major occurrence are little...
