Multi-period optimal power flow (OPF) is a basic tool to achieve optimal operation of a power system with energy storages devices and renewable sources. A novel convex relaxation based decomposeition algorithm is proposed in this paper to solve the full AC multi-period OPF with energy storages and renewable sources. Based on alternating direction method of multipliers (ADMM), the original time-correlated...
In this paper, the optimization of a microgrid operating in a “urban district-like” environment is considered, combining both the optimal scheduling of the microgrid sources and demand response strategies, implemented in the district buildings. In particular, the overall system is optimized in order to schedule generation plants, storage systems, electrical vehicles, deferrable and variable loads...
This paper present brief description of a Microgrid development project currently in progress. Initially, then Malaysian renewable energy policy is briefly highlighted. The objective of having Microgrid is discussed. The main components of Microgrid and the technique on how the Microgrid central controller was developed is also explained. The result from simulation study of Microgrid system in the...
A microgrid is a secondary (low voltage) network capable of supplying part or all the power needed by the connected users. It is composed by solar panels, energy storage devices, diesel plants, microturbines, and all other distributed generation technologies available for connecting to the low voltage grid. As a relatively new trend, there is still a need for developing analysis in different fields...
Future power networks will include various local sources (LS)s as alternatives to centralized power generation in sustaining local loads. The cost of electrical power at LSs depends on the specific kind of the source, e.g., operating on renewable energy, using energy storage equipments, being a fuel cell, etc. In general, the cost will be proportional to the provided active power. In this paper we...
