Active Distribution Networks

Voltage control in active distribution networks must adapt to the unbalanced nature of most of these systems, and this requirement becomes even more apparent at low voltage levels. The use of transformers with on-load tap changers is gaining popularity, and those that allow different tap positions for each of the three phases of the transformer are the most promising. This work tackles the exact approach to the voltage optimization problem of active low-voltage networks when transformers with on-load tap changers are available. A very rigorous approach to the electrical model of all the involved components is used, and common approaches proposed in the literature are avoided. The main aim of the paper is twofold: to demonstrate the importance of being very rigorous in the electrical modeling of all the components to operate in a secure and effective way and to show the greater effectiveness of the decoupled on-load tap changer over the usual on-load tap changer in the voltage regulation problem. A low-voltage benchmark network under different load and distributed generation scenarios is tested with the proposed exact optimal solution to demonstrate its feasibility.

Marginal Price

<p>The chances of congestion in deregulated market are quite high as compared to the monopolistic market as the customers would like to purchase electricity from cheapest available sources. Ways for Congestion management are: Generation rescheduling, Interruptible load curtailment, Transmission system expansion etc. Transmission expansion planning is the last way for congestion management if congestion is not managed by Generation rescheduling and Interruptible load curtailment. A high mean of Locational marginal price (LMP) at a bus indicates no access to cheap generation and a low mean of LMP indicates access to excess cheap generation and no access to enough loads.  Hence, constructing a new line between two buses with low and high mean of LMP will allow the dispatch of the excess cheap generation and flow of energy from low LMP bus to high LMP bus due to price potential difference. Consequently, the flatness of price profile is improved. The final plan is selected by economic analysis.</p><p><strong>Journal of Advanced College of Engineering and Management</strong>, Vol. 3, 2017, Page: 49-54</p>
