A lot of attention is being paid to wind energy due to the focus on renewable energy. Malaysia is situated in the equatorial region and its climate is governed by the monsoons. Wind resource in Malaysia varies from one location to another. Wind speed is better offshore compared to onshore, so more contribution by offshore wind powers in terms of electricity generation. Wind energy potentiality and techno-economic feasibility of offshore wind farms in Malaysia is investigated in this paper. Research was conducted using HOMER software to assess the potential of wind energy along the South China Sea coastline. This study indicates the best sites to set up offshore wind farms in Malaysia while costs associated for wind energy generation are calculated. Two model of the wind turbines Vestas V-47 and V-80 are taken for economic feasibility analyses. Investment, operation and maintenance costs have been evaluated for offshore wind energy. Feed-in tariff policy effects energy price and wind farms profitability were analyzed.

“…The construction of the SSSC is close from the STATCOM constructions but differs in connection as it is connected in series with the transmission grid ( as seen in figure 5, so the injected voltage should be controlled to be in quadrature with the current of the grid, and that is controlled normally by using dq controller in order control the V q of the injected voltage so to be in quadrature and in phase with I line as V q and V d represents the converter voltage. The control strategy is performed through a Voltage source converter (VSC) that is attached with the secondary side of the series transformer [11]. …”

The demand of reactive power in the last mile of the networks is increasing by the time due to the change of loading types by time, beside increasing the total demand itself where new technologies are being introduced depend mainly on different types of electrical support such as electrical cars and more electronic devices in consumption process [1]. This expected situation would lead to take into consideration new approaches in the last mile substations in order to mitigate the drawbacks of the conventional legacy and that by providing more functions in the last mile substations that could provide more flexibility and functionality regarding voltage level, reactive power (RP), amount of demand and losses [1]. This paper focuses the light on the consideration that are taken in designing a distribution transformer that provide additional abilities in regulating the voltage and controlling the RP that is injected in the distribution network (DN) by using a fractional rated converter that is attached partially with the windings of the transformer. This approach aims mainly to enhance the unit with more flexibility in controlling the flow the of the RP at the last mile of the network in order to decrease the losses that are caused by transmitting RP through long transmission networks. The design of the power electronics (PE) modules is detailed and its functionality in compensating Var power is discussed. This approach contributes in meeting the future expectations of the low voltage (LV) networks changes and loading, this contribution is comprised of providing the substation unit with fractional rated power electronic converter that is attached partially with the winding of the LV transformer to provide the load with a specific level of its demand from RP, whereby the solid state switches are controlled according to the immediate need for Var control and support in low voltage (LV) networks [1].

“…Lots of Distributed Generation (DG) may be installed and work in parallel with electrical power networks as one of the best alternatives to solve environmental problems and to cope with rising energy prices and costs of power plant construction. Distributed generation is any type of electrical generator or static inverter producing alternating current that (a) has the ability for parallel operation with the power distribution system, or (b) is designed to operate separately from the utility system and can feed a load that can also be fed by the power electrical system [1]. The installed DG may make a contribution to improve quality of power, minimize peak loads and eliminate the need for reserve margin [2] [3].…”

This paper proposes a robust hybrid anti-islanding method for Inverter-based Distributed Generation (DG). This method is based on Active and passive detection techniques. Active anti islanding technique generates disturbances at the output of the distributed generation by Positive feedback and Continuous feedback signal injection which is based on DQ implementation. On the other hand passive anti islanding technique detects islanding by measuring voltage, frequency, active and reactive power and total harmonic distortion (THD). This technique uses resistive, capacitive and inductive connected in parallel RLC load and compares the performance of the technique with and without the controller. This method of control is shown to be robust, able to detect islanding under different types of loads, and fast in response. Possible islanding conditions are simulated and verified with full analysis.
