“…The stand-alone system consists only of the DG sources listed above and does not incorporate existing grid power [1][2][3][4][5][6]. This type of system may allow electricity to be provided free-of-charge to consumers once the practical constraints of sizing, siting and environmental concerns are overcome.…”

This paper presents look-ahead energy management system for a grid-connected residential photovoltaic (PV) system with battery under critical peak pricing for electricity, enabling effective and proactive participation of consumers in the Smart Grid's demand response. In the proposed system, the PV is the primary energy source with the battery for storing (or retrieving) excessive (or stored) energy to pursue the lowest possible electricity bill but it is grid-tied to secure electric power delivery. Premise energy management scheme with an accurate yet practical load forecasting capability based on a Kalman filter is designed to increase the predictability in controlling the power flows among these power system components and the controllable electric appliances in the premise. The case studies with various operating scenarios demonstrate the validity of the proposed system and significant cost savings through operating the energy management scheme.

“…Alternative energy sources are inherently non-polluting, free in their availability, and continuous [2]. However, their applications in conventional distribution systems are limited due to high initial cost and reliability issues [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. An easy and effective approach in utilizing solar energy is to convert it directly to electrical energy using Photovoltaic (PV) technology [4].…”

This paper presents the development of an effective approach for design, simulation and analysis of hybrid PV-wind generating systems which is based on discrete optimization of cost function and balance of energy. The total capacities of renewable systems are computed based on the estimated annual power consumption, average wind speed and sun radiation. To improve the performance of the system under different environmental conditions, Maximum Power Point Tracking (MPPT) of the photovoltaic system and blade angle pitch control of wind turbines are included. A discrete cost function is defined and optimized to determine optimal design options with minimum number of PV and wind units capable of supporting the yearly demand load. Finally, system simulation and energy balance calculations over a period of three years are used to compensate for design errors caused by the discrete nature of the optimization approach. Main contributions are the inclusion of renewable systems configurations, capacities, environmental factors and maximum power point tracking in the optimization procedure.

The focus of the world on renewable energy sources is growing rapidly due to its availability and environment friendliness. However, the renewable energy influenced by natural conditions is being intermittent, it is difficult to accomplish stable energy supply only by one kind of renewable energy source. In order to achieve reliability, it is necessary to integrate two or more energy sources together in an optimal way as hybrid energy system. Optimal allocation of sources, unpredictable load demand, intermittent behaviors of sources, and charging and discharging of storage devices are the major challenges in operating a hybrid energy system. A new controller algorithm is developed and implemented in controller hardware to overcome the above issues. The controller is incorporated in biomass gasifier-based hybrid energy system in a university campus at south India. A case study is carried out in real-time at the site for a typical day. From the experimentation, it is estimated that the annual savings in the operating cost are Rs 375,459.00 ($8475.4) for the optimal allocation of the sources by the controller.
