Latest researches related to Wide Area Measurement Systems (WAMS) recommends the development of a cost-effective FPGA based phasor measurement unit for developing a real time synchrophasor network. This paper presents an algorithm for an FPGA based Phasor Measurement Unit (PMU) modeled using Xilinx Vivado System Generator design suite. The backbone of the proposed PMU algorithm is the Non Recursive...
The higher penetration of Non Dispatchable Energy Sources inspite of its many obvious benefits may cause system stability into jeopardize. Also its ability to increase system reliability needs to be examined due to its inherent intermittency. This problem can be overcome by using a mix of renewable energy sources and also the use of storage units. A Microgrid consisting of wind and PV connected to...
The existing power grid is experiencing sustaining energy shortage. Distributed generation (DG) including wind energy, solar energy can be a solution for the energy shortage in the existing power grid. Distributed generation is the generation of power using small sized generators that produces electric power at low voltage levels and is connected to the distribution network directly near the load...
The black start units in a typical hydro-thermal power system will be the hydro power plants since they require very small power to restart after a total shut down, compared to a thermal power plant. They are supposed to start up and supply cranking power to the non-black start units in the system like steam and nuclear power plants. So the time taken for the hydro power plant to start up and start...
The emerging potential of renewable based electricity generation systems, diversity of storage and various loads are interconnected through the microgrid structure. Techno-economic study to design and develop a biomass based hybrid renewable energy systems for the microgrid application for a typical rural site is described in this paper. Optimization on size of the sources of hybrid system has been...
Absence of a generalized pricing method is one of the key issues with renewable energy generation. Each utility uses a different method for pricing energy. The proposed model gives a generalized method for determining energy price for generating companies, independent power producers, regulatory commissions etc. It incorporates both the economic and performance based factors in the pricing model....
This paper proposes a DC linked hybrid solar photovoltaic/wind energy system for stand-alone applications. Solar and wind energy are utilized as primary energy sources and battery unit is considered as storage to meet the primary load demand. Loads are considered according to their priority such as primary, deferrable and dump loads. Among these loads primary load is having highest priority. Ratings...
This paper proposes a multiple input power conditioner topology to integrate intermittent nature of renewable sources such as solar, wind, etc. The proposed power conditioner makes the interface among solar PV and wind generator to obtain well-regulated output voltage. The regulated energy can be transferred into the load through PWM inverter. The paper is mainly focused on the integration and voltage...
Microgrids are the platforms to integrate DERs into distribution systems. The optimal management of such systems has gained importance in the era of competitive power market. This paper mainly concentrates on functional and logical modelling of various components and strategies of microgrids, thereby proposes an objective function to get economic sizing and scheduling of DERs in a microgrid. A case...
This paper presents a new set of methodologies and tools to implement multilateral trades in a restructured electricity market. Loss minimization is made an objective, realized through elasticized transmission charge. This charge is designed to acts as a financial instrument that penalizes deviation from least loss formulation. To reduce its impact coalition formation is envisaged in a cooperative...
