Transmission system is one of the most important parts of the restructured power system. Insufficient or inappropriate expansion of transmission system is considered to be a major barrier to competition in electricity market. Therefore many researches have been focused on developing suitable approaches for transmission expansion planning in deregulated power systems. This paper presents a new ...

مطالعه و بررسی شبکه قدرت و رفع نقاط ضعف آن به منظور عملکرد صحیح، همواره به طور پیوسته و مداوم مورد نیاز می باشد. در برنامه ریزی بهره برداری فرض بر کفایت تجهیزات موجود در شبکه است و هدف این است که با استفاده از تجهیزات موجود، انرژی الکتریکی مورد نیاز مصرف کنندگان به صورت مطمئن و مقرون به صرفه تامین شود. برنامه ریزی توسعه شبکه وقتی نیاز است که شبکه کفایت لازم جهت تامین انرژی مورد نیاز مصرف کنندگا...
transmission network expansion planning (tnep) is an important component of power system planning. itdetermines the characteristics and performance of the future electric power network and influences the powersystem operation directly. different methods have been proposed for the solution of the static transmissionnetwork expansion planning (stnep) problem till now. but in all of them, stnep pr...
An important factor to be considered in electric power system expansion planning is the security of service that the system is able to provide. In restructured power systems, variables such as agents’ profit or Locational Marginal Price (LMP) variances are considered in transmission expansion planning. To have a secure network this plan would be refined for simulated contingencies. This p...
A new market based approach for transmission expansion planning in deregulated environments is presented in this paper. In this approach, transmission-planning decisions are made based on the electric power market conditions. The main contribution of this research is 1) Introducing a new probabilistic tool for analyzing the electric market conditions, 2) Defining new criteria for ranking transm...
Although significant private investment is absorbed in different sectors of power systems, transmission sector is still suffering from appropriate private investment. This is because of the pricing policies of transmission services, tariffs, and especially for investment risks. Investment risks are due to the uncertain behaviour of power systems that discourage investors to invest in the transm...
Renewable energy policies, such as the Renewable Portfolio Standard, arising from increasing environmental concerns have set very ambitious targets for wind power penetration in electric power systems throughout the world. In many cases, the geographical locations with good wind resources are not close to the main load centers. It becomes extremely important to assess adequate transmission faci...
In recent years, significant research efforts have been devoted to the optimal planning of power systems. Substation Expansion Planning (SEP) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future load demand. The large number of design variables and combination of discr...
