    DC microgrid as a solution for utilisation of solar photovoltaic sources
    (Institute of Electrical and Electronics Engineers, Inc., 2016-12) Bandara, AIMH; Binduhewa, P; Ekanayake, J; Rajapakse, A; Prasad, WD
    MicroGrid (MG) is a convenient solution to integrate renewable energy sources to the existing power network. Though ac MicroGrids are widely studied, researches are focused towards the implementation of dc MicroGrids in order to improve the utilization of renewable sources with dc power output. In this study a MicroGrid architecture for commercial buildings and domestic houses with solar photovoltaic (PV) as the renewable energy source is proposed. The dc MicroGrid was implemented in PSCAD/EMTDC software package and simulations studies were conducted to validate the operation.

    Design of a small electric vehicle charger with multi-ports
    (Institute of Electrical and Electronics Engineers, Inc., 2018-09) Wijesekera, A; Binduhewa, P; Samarasinghe, R; Abeygunawardana, S
    In developing countries, small vehicles such as three-wheelers are one of the most commonly used public transportation method and considered as an efficient way to travel in the traffic. Even though the commonly used type is based on fossil fuels, fully electric small vehicles are commercially available and developing. The biggest hurdle for the expansion of small Electric Vehicles (EVs) is the unavailability of charging stations around the country. This paper presents a charging station for small EVs. The proposed charging system has the capability of charging multiple small EVs simultaneously. Also, the charging station is capable of bi-directional power flow and thus small EVs can support grid when required. The performances of the controllers are verified by simulating the system in PSCAD/EMTDC. Finally, a cost analysis also was carried out to find out the financial feasibility.

    Voltage control of three phase distribution systems with minimum cost
    (IEEE, 2021-07) Manamperi, DI; Dissawa, LH; Arachchige, LNW; Binduhewa, P; Ekanayake, JB; Adhikariwatte, W; Rathnayake, M; Hemachandra, K
    Prevention of voltage rise under minimum cost in distribution networks with high PV penetration is considered in this study. On load tap changing (OLTC) transformer and PV inverters are used as controllable devices. The actual cost minimization of transformer tap change, inverter curtailment and line losses is considered as the objective of the optimization problem. Sequential use of mixed integer second order cone (MISOCP) program is used as the optimization technique. Simulations results demonstrate the capability of voltage regulation under minimum cost. Exactness of the generated solutions are validated after comparison with load flow.
