Due to their high inter-temporal variation and intermittence, large-scale integration of the new energies, such as wind power and photovoltaic power, will pose great challenges to the safe and stable operation of power system. Analysis on gird stability and adaptability before integrating the new energy should be made. The paper investigates all kinds of restrictions and assesses each constrained capacity from the perspective of steady-state and transient voltage, frequency stability, cross-section transmission limit and peak load regulating capacity, respectively. Then the comprehensive evaluation on the capability to accommodate new energy for a power grid is accomplished. Take a practical grid for example, its accommodation capacity for new energy is calculated based on the above-mentioned method, which provides a theoretical basis for the grid to accommodate new energy and planning and construction of new energy.

<div>The changing energy landscape due to the large scale integration of renewable energy and shutting down of conventional thermal plants has opened up the potential of alternate sources in the blackstart services market. Grid forming wind turbines can do controlled islanded operation independent of an external grid voltage and thus, participate in network restoration from the start. However, it is necessary to study the capability of wind turbines to deal with the demanding energization transients in a controlled and stable manner. This work investigates the feasibility of using virtual resistance in the wind turbine converter control to reduce transients during self-transformer inrush and sympathetic interaction from downstream string transformers. This can eliminate the need for pre-insertion resistors during sequential energization. The sensitivity of the AC current and voltage output along with DC link transient to the virtual resistance parameters has also been analyzed using PSCAD simulations. Finally the effectiveness of the proposed method for offshore network energization by a grid forming wind power plant has been tested by comparing to results for a pre-insertion resistor.</div>

And Function

Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and function. In higher plants, such as in animals, the intercellular communication is fulfilled through chemical messengers. These specific compounds in plants are called phytohormones, or in a wide sense, bioregulators. Even a small quantity of these endogenous organic compounds are able to regulate the operation, growth and development of higher plants, and keep the connection between cells, tissues and synergy beween organs. Since they do not have nervous and immume systems, phytohormones play essential role in plants’ life. Orv. Hetil., 2014, 155(26), 1011–1018.
