“…To obtain the real-time optimal control signals of the developed Model Predictive Controller (MPC), the stochastic dynamic programming (SDP) approach is used. In addition, some previous studies investigated the optimal scheduling of MGs, taking the peak shaving, valley filling, and BESS operation costs into consideration as significant contributors to the MG operating cost [16][17][18]. Authors in [19] inspect the optimal power flow in the grid-tied MG including renewables and distributed generation units by establishing a trade-off between the economic benefit and the reliability of the system.…”

Due to the great renewable integration capability of Microgrids (MG), reliability, resiliency and stability improvement, MGs play a crucial role in the next generation of electrical power networks. Besides, MGs provide significant potential economic and environmental benefits. However, the intermittent nature of renewable sources necessitates utilising energy storage devices, which would impose new challenges to the energy management of MGs. This paper proposes a centralised optimal power flow controller to minimise the operation cost of distributed microgrid systems while satisfying the technical constraints, considering the battery energy storage depreciation, transmission losses, and dispatchable units' characteristics. Due to the extensive computational time required to solve the nonlinear optimisation problem, the distributed microgrid system is formulated as a Mixed Integer Linear Problem. To investigate the performance and functionality of the proposed approach, it is applied to an actual case study at Griffith University, consisting of four MGs. The obtained results confirm the cost-effectiveness and applicability of the proposed model and control approach.

<abstract> <p>Power sector plays a crucial role in the development of a country. Rise in population and industrial expansion in developing countries are reason to burdenize the central grid. Pakistan is a country in its developing stages. About 58% of its total energy generation is contributed by fossil fuel based conventional plants for which the fuel costs plenteous amount. In these circumstances it is indispensable to exploit naturally available renewable resources for electricity generation. This study proposes a hybrid hydro-kinetic/Photovoltaic/Biomass system integrated with grid to serve electricity in a residential area of district Kotli in AJK Pakistan. By evaluating available resources and total load demand data of residential consumers, a system design is modelled in HOMER to get techno-economic and optimal design analysis of the purposed system. Using several configurations and combinations of available energy generation systems and then by comparing their results, the most optimum system design is achieved in terms of initial cost, operating cost, cost per unit and net present cost of the system. To further refine the results, the effect of variations of different parameters like load demand, water flow speed and solar irradiance on system is investigated by performing sensitivity analysis on the system. Final results demonstrate that the purposed system is cost-effective and efficient to meet the load demand.</p> </abstract>
