“…From Equations (8) and 9, we can see that when the power imbalance is small, a sufficient reserve capacity can be retained in the optimization dispatch through the above constraints. Equation (8) indicates that the primary reserve of the system is sufficient to cover the power loss and maintain the power balance, while through Equation 9we determine the reserve capacity based on the ramp rates of different governors.…”

“…However, limited by the storage technology and costs, the electric energy cannot be stored in large quantity. Some scholars and engineering experts therefore put forward the virtual synchronous generator (VSG) technology, which makes it possible for the grid connection of the new energy units using the power controller containing power electronic converters to share the features of the grid-connected synchronous generator, such as inertia, damp, frequency regulation and voltage regulation [7][8][9]. During this process, the rotor motion equations for the VSG and primary frequency regulation are also introduced.…”

With the large-scale integration of renewable energy sources (e.g., wind power), the system inertial response and primary frequency regulation are affected. The virtual synchronous generator technology, which makes it possible for wind power units to adjust the frequency, provides a new way of approaching this problem. In this paper, we set up the related constraints that fit the optimal dispatch framework with a primary reserve representing the primary frequency response between the conventional synchronous generator and the wind power units, and the technical parameters of the virtual synchronous generator. Meanwhile, we use the robust day-ahead optimization dispatch model considering the wind power integrated primary frequency control in the real-time operation with the scenario of the wind power output showing the uncertainty of wind power. Based on the model, we identify the key set using an iterative method and obtain the maximum power loss. Through the proposed model, we could provide the day-ahead unit output and real-time primary reserve, thus ensuring the reliable operation of the system. Finally, the effectiveness of the proposed method is verified by a computational experiment.

In the generation, the most widely used generator is synchronous generator (SG) but its cost of producing per kilo watt (kW) power is higher than induction generator (IG). There are many advantages of IG over SG like, IG has small size for per kW output power production it means that the energy density of IG is higher than SG, when operates in parallel IG runs without hunting problem. IG can recover the energy with relatively simple control. IG is an alternative source to convert mechanical energy into electrical energy. Some problems are associated at distribution and generation level when IG operates in an isolated electric system. These problems are mainly caused by in linear changes in load. It results in loss of system reliability. The quality of voltage and frequency also get affected. So, to enhance reliability to control voltage & frequency, a flexible method with power electronic converter is used which control the dynamics of system and provide electrical power support as well simultaneously. When this converter emulates with its control mechanism, it works like a real synchronous generator which is called as VSG. This paper presents the distribution-generation system in collaboration with IG and VSC. VSC controller are designed on the basis of d-q model of converter. Performance of this control strategy is verified through Matlab/Simulink. The simulation result represents the actual behavior of the system against the non-linear loads. It shows the optimization of power and keeping the voltage frequency under a permissible limit.
