Increasing penetration of renewable energy is posing challenges to stable operation of the power system. An important stability consideration is the small signal stability, which is characterized by Hopf bifurcation. The system operator can use ancillary services to maintain sufficient Hopf bifurcation margin to ensure stability. This work proposes a method to identify the optimum locations for ancillary services to improve Hopf bifurcation margin. The forecast uncertainties related to load and renewable based generation has been handled using boundary power flow based eigenvalue analysis. Simulation studies were performed on WSCC 9 bus system and New England 39 bus system. The accuracy of proposed method is proved by comparing the result with Monte-Carlo method.
可再生能源的日益普及对电力系统的稳定运行提出了挑战。一个重要的稳定性考虑因素是小信号稳定性，其特征是Hopf分岔。系统操作者可以利用辅助服务来维持足够的Hopf分岔余量，以保证系统的稳定性。本文提出了一种确定辅助服务最优位置的方法，以提高Hopf分岔裕度。利用基于边界潮流的特征值分析方法处理了负荷和可再生能源发电的预测不确定性。对wscc9公交系统和New England 39公交系统进行了仿真研究。通过与蒙特卡罗方法的比较，证明了该方法的准确性。

This paper deals with the performance analysis of direct torque controlled–squirrel-cage induction motor (DTC-SCIM) drive. The performance of classical switching table based DTC-SCIM has been compared with that employed with space-vector pulse width modulation (SVPWM). A PI based speed controller is employed in outer loop for both the schemes. The model of DTC-SCIM drive system is developed and simulation is done in closed-loop. The drive performances have been observed for various step changes in load torque and reference speed. The simulation results have been presented and discussed in detail.

Present work focused on the design of a robust optimal tilt-integral-derivative controller (TID) for frequency regulation of an isolated power system against load variation and intermittent fluctuations of RERs. Dragonfly algorithm (DA) is applied to explore the optimal gains of TID controller based on integral error criterions. To quantify the mastery of DA tuned TID controller, the obtained results are compared with the results of conventional and fractional order controllers for the similar test system. To curtail controller design effort, reduced order model (ROM) of the actual test system has been derived by using balanced truncation algorithm. Finally, robustness of the developed control system is affirmed by using Kharitonov's theorem. The simulation results depict that the proposed control system is robustly stable under the wide variation of system parameters.

This paper proposes a new bio-inspired Salp Swarm Algorithm (SSA) to solve the Economic Load Dispatch (ELD) problem considering valve point loading effect. The main inspiration of SSA is the swarming behavior of salps when navigating and foraging in oceans. The ability of salps to form a chain for achieving better locomotion using rapid coordinated changes and foraging has been successfully exploited in this paper to attain various objectives associated with ELD problems of power system. This algorithm has only one controlling parameter which is updated adaptively over the course of iterations for exploration and exploitation. To obtain the optimal solution, the proposed algorithm is validated on test systems consisting of 10 and 40 generating units.

India being a developing country has the need of both addition in generation and replacing the old ones commensurate with ever-increasing demand in the domestic, agricultural, commercial, and industrial sectors. With Demand Side Management (DSM) resorted to effectively, however, there exists potential of shaving peak, and consequently to some extent energy in this important infrastructure of economy. Having an installed capacity of about 81 GW from Renewable Energy Sources (RES) out of a total of 360 GW by July 2019 it has an ambitious plan for significant addition of renewables reaching the level of 175 GW (100 GW from solar including 40 GW of rooftop, 60 GW from wind, 10 GW from bio-mass, and 5 from small hydro), and 275 GW respectively by the end of country’s 13th (March 2022) and 14th five-year plan (March 2027). Thus, as estimated, by 2030 it may be in a position to contribute about 48% from renewables only. This is based on detailed studies on load forecasting in different sectors geographically over pan-India in different time-frame followed by estimation of potential from RES. The latter consist of development from solar, wind, biomass, waste, etc. both off-grid and on-grid. Finally planning has been carried out simulating likely scenario at different point of time with system having sizeable penetration of renewables in the overall requirement of generation to meet the electricity demand. Technological developments, standardization, and regulatory measures have paved the way for large-scale integration of renewables to the Extra High Voltage (EHV) grid by pooling the surplus from one region for haulage to other regions for distribution of electricity. In the process gradually conventional fossil-fuel based generating plants are being phased out, though it continues with still addition of the backlog in the system. However, in the process Plant Load Factor (PLF) of such type of generation is coming down enabling lessening pollution too. With economy of scale and more accuracy achieved in predicting intermittent generation from renewables, it has already been possible to achieve much reduction in per unit charges of electricity from RES, notably from both, solar and wind.In the paper based on Long-Term Load Forecasting, results of studies to find out optimal mix of existing conventional fossil-fuel based generation integrated with renewables from various sources have been depicted based on computation.

In general, the electrical energy is transmitted from solar panel to the grid through a boost converter along with inverter. In recent times, single state converters (like Z-source inverters and split source inverters (SSI)) are being used for grid-connected solar systems for improving the conversion efficiency and voltage gain. Among the single stage converters, SSI has addition merits like lower device count, lower switch voltage stress, which is most suitable for solar applications. However, the solar system requires a higher voltage gain converter because of its low output voltage ratings. In this regard, voltage gain of conventional SSI is enhanced using switched inductor structures and it has presented in this paper for solar energy applications. This proposed single phase high gain switched inductor split source inverter (SISSI) has a higher voltage gain compared to the other conventional topologies. And also, SISSI has a reduced passive component count, lesser inductor size, capacitor size and improved efficiency than conventional topologies. The proposed SISSI has been implemented using MATLAB/Simulink for solar applications. And, the analysis is carried out for different irradiation changes. Also, the 100W prototype of SISSI was developed by using a DSP control board, IGBT switches. And, the proposed SISSI topology compared with existing ZSI, qZSI and SSI topologies in different aspects like voltage gain, passive component size, number of components and efficiency.

In this paper a Biquad Filter called Universal Filter is designed for reducing power quality-based problems in power distribution systems. Increased use of solid-state power electronic based devices and loads requires shunt active power compensation techniques for mitigation. The Biquad Active Filter is a second order filter offering all four basic filters viz high pass, band pass, low pass, notch filter. In this paper bandpass and low pass filter are of prime importance as they are used for estimating the peak of the load current. It can be tuned by varying the quality factor and center frequency. The compensation technique is designed in MATLAB environment and its performance is experimentally verified using dSPACE- 1104.

In this work a SMC based Nine Switch Converter topology has been used to integrate 2 different Renew able Energy Sources (RES) which feeds power to local time varying load. The Hybrid Autonomous System (HAS) consists of a 22Kw Self Excited Induction Generator (SEIG) based micro-hydro system and a Photovoltaic System. This system is also equipped with a Battery Energy Storage System and feeds power to a concentrated time varying load. The mere advantage of NSC is that it has a DC-link which helps in power control between SEIG and load. The major advantage of SMC based NSC is that continuity of power flow to the load is maintained even if the sources (SEIG & PV) are disconnected. Again the source side is unaffected if any disturbances is prevailed in load side. A couple of decoupled control strategy is designed for SEIG and load side control. This HAS is subjected to 3 different types of time varying loads i.e. Linear, Non-Linear and Dynamic Loads and their analysis is discussed. The above mentioned system was simulated and validated using MATLAB/Simulink environment.

This paper presents long term performance analysis of 15.6 kW hybrid solar photovoltaic system installed at College of Science and Technology, Rinchending, Bhutan. Data for one year from Photovoltaic hybrid system is collected and analysed. Losses due to shading are also analyzed and found that shading affects only in winter. Energy and economic performances of the system were also calculated using relevant empirical formulae. From the result, the estimated cost of generation is US$ 0.13/kWh or Nu.9/kWh. To install PV system is not financially viable at current electricity tariff in Bhutan, however due to its clean energy and environmental advantage, solar energy harvest is always preferable despite the high cost factor comparing to cheap hydropower in Bhutan.
