PJM Interconnection LLC is a Regional Transmission Organization in the United States. It is part of the Eastern Interconnection grid operating an electric transmission system serving all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. PJM, headquartered in Valley Forge, Pennsylvania, is currently the world's largest competitive wholesale electricity market. More than 830 companies are members of PJM, which serves 60 million customers and has 167 gigawatts of generating capacity. With 1,325 generation sources, 59,750 miles of transmission lines and 6,038 transmission substations, PJM delivered 682 terawatt-hours of electricity in 2009.Started in 1927, the pool was renamed the Pennsylvania-New Jersey-Maryland Interconnection in 1956. The organization continues to integrate additional utility transmission systems into its operations. Wikipedia.

Renewable energy resources, such as wind and solar, have become important parts of today's generating resource mix. Along with them, these resources also bring their inherent characteristics of variability and uncertainty. Hence, resource planners must be adaptable to accommodate these resources in conducting resource planning. Understanding their impact on the electric grid must be prior and critical. In this paper, we have studied the potential impact of solar energy penetration in a particular location of PJM electricity market. Key economic and system variables that were analyzed include system production cost, market prices (average zonal prices), congestion (both hours and dollars), and transmission losses. We find that significant penetration of solar energy resources can produce system-wide economic benefits in the respective transmission areas as well as the entire system. © 2011 IEEE. Source

Smart-Grid has been a buzzword in the power industry for some time. While smart-grid could mean differently to different entities, our understanding of it has been quite limited. In this paper, we describe the identifiable developments that seem to relate to so-called smart-grid and that can have impact on the grid and market operations. Obviously, not all developments around smart-grid would have meaningful impact on the market operation, while those that do have impact, have varying degrees of impact, depending on many factors. These various developments include, but not limited to, substation automation, phasor measurement, smart appliance, demand response, electric vehicles (P(H)EV), energy storage, micro-grid etc. We, then, categorize them based on their impact on specific part of power system, such as transmission and distribution, generation and load. We further select those developments that can have significant impact on the electricity market operation as well as market simulation. We then try to present various issues and challenges associated with these selected developments in terms of incorporating them in the market operation and simulation, to account accurately for their unique physical characteristics and economic nature. © 2011 IEEE.
