Load profile synthesis and wind power generation prediction for an isolated power system

Abstract: This paper investigates the load composition by load survey study and predicts the wind power generation with a probabilistic network for an isolated power system. The power consumption by each customer-class with the application of load patterns and the total power consumption of all customers within the same class can be obtained and calculated. Probabilistic neural network (PNN) solves the wind power generation based on the wind speed for an offshore island in Taiwan. With the hourly wind speed and load composition, the power generation of diesel generators has been obtained. Results of this study demonstrate that wind power generation can economically and effectively replace the generation of the diesel power plant and provide partial power supply capability for the net peak load requirement

Power quality measurements of wind energy converters with full-scale converter according to IEC 61400-21

Abstract: Wind energy has reached remarkable shares in the electrical energy production in many countries worldwide. However, the connection of multi-megawatt wind farms leads to the necessity to examine the impact on the grid closely. The International Electrotechnical Commission (IEC) developed and released the IEC-standard 61400-21 as part of the IEC 61400 standards for testing and assessing power quality characteristics of grid-connected wind energy converters (WECs) in a consistent and accurate way. To easily compare WECs of different types it defines a measurement excerpt that states the key power quality characteristics: wind turbine specifications, active and reactive power output, flicker, harmonics, control of active and reactive power, protection, voltage dip response and reconnection time. Based on the measurement results in that excerpt the maximum grid connection capacity can be determined for a chosen connection point in order to fulfil the given national or international power quality requirements. Different wind turbine types have different power quality characteristics. As a pioneer in advanced WEC technology and grid integration, ENERCON has developed a range of certified WEC types to address the most demanding international grid codes. In recent years the power quality characteristics of all these types were tested and certified according to IEC 61400-21 by independent testing institutes. Reasons for the good power quality characteristics can be found in the design of these WECs based on an annular generator, injecting power via full-scale power electronics and associated control systems. Additional control features like soft-start without inrush currents, Storm Control and wind farm control systems to control the voltage, power factor or reactive power can, to a certain extent, even improve power quality in power systems.

Modelling renewable energy impact on the electricity market in India

Abstract: Renewable power generation development, most notably for wind and solar, has taken off at a rapid pace in India especially in the last 4 years. While these developments have many positive aspects, a rapid shift in balance of baseload and intermittent generation must be assessed carefully to ensure the share of renewable power generation increases without compromising system security and economics. Seasonal and spatial variability of wind, and to a lesser extent that of solar, can render these resources to have low availability for a significant part of the year leading to an increase in unserved energy, i.e., deteriorate system reliability. The intermittency of generation also impacts on inter-state power flows and lead to higher congestion in the grid. Climate model results provide a rich set of information on the nature of solar/wind variability that can be embedded in an electricity market simulation tool to assess these impacts on prices, generation dispatch and power flows. We have developed a modelling analysis for the Indian national electricity market informed by CSIRO climate model results. We have assessed the added costs arising from intermittency to put in perspective the true costs and benefits of renewable power. We have focused on the near-term developments in 2017 to show how some of the high renewable growth scenarios included in the Indian National Electricity Plan may imply significant pressure on inter-state/region transfer capability, and lead to a significant worsening of system reliability. The outcome of our modelling analysis suggests that a more orderly and balanced development of renewable and conventional power generation capacity is needed with a stronger focus on system economics and security.
