The increasing penetration of renewable energy in recent years has led to more uncertainties in power systems. In order to maintain system reliability and security, electricity market operators need to keep certain reserves in the SecurityConstrained Economic Dispatch (SCED) problems. A new concept, deliverable generation ramping reserve, is proposed in this paper. The prices of generation ramp...

How to best site reserves is a leading question for conservation biologists. Recently, reserve selection has emphasized efficient conservation: maximizing conservation goals given the reality of limited conservation budgets, and this work indicates that land market can potentially undermine the conservation benefits of reserves by increasing property values and development probabilities near re...

The same forces that lead to changes in participation in the labor market can also affect the extent of criminal activity. To analyze such interaction we construct a search-theoretic model where labor market participation, labor market outcomes and crime are determined jointly. The model is calibrated to US data focusing on females. The main finding is that changes affecting the labor market, s...

one of the significant strategies of the power systems is economic dispatch (ed) problem, which is defined as the optimal generation of power units to produce energy at the lowest cost by fulfilling the demand within several limits. the undeniable impacts of ramp rate limits, valve loading, prohibited operating zone, spinning reserve and multi-fuel option on the economic dispatch of practical p...

There are three types of compact spinning system on the market now: pneumatic system, mechanical system and mechanicalpneumatic system. The pneumatic system is the dominant one, which adopts perforated drum, perforated apron or lattice apron as condensing elements.5,6 The roving strand emerging from the front roller nip is condensed by negative pressure airflow produced by the aforementioned el...

This paper examines interactions between the labor market and crime. It seems reasonable to believe that changes in policy or technologies that affect the labor market might affect the extent of criminal activities, and vice versa–changes in the crime sector can affect the labor market. To analyze these interactions we construct a search-theoretic model where labor market outcomes and crimes ar...

Competitive structure of power markets causes various challenges for wind resources to participate in these markets. Indeed, production uncertainty is the main cause of their low income. Thus, they are usually supported by system operators, which is in contrast with the competitive paradigm of power markets. In this paper, a new strategy for increasing the profits of wind resources is proposed....

Due to the volatile nature of wind and photovoltaic power, wind farms and solar stations are generally thought of as the consumers of ramping services. However, a microgrid (MG) is able to strategically integrate various distributed energy resources (DERs) to provide both energy and ancillary services (ASs) for the bulk power system. To evaluate the ramping capabilities of an MG in the joint en...

We provide a model of the impact of bank mergers on loan competition, individual reserve management and aggregate liquidity risk. Banks hold reserves against liquidity shocks, refinance in the interbank market and compete in a differentiated loan market. A merger creates an internal money market that induces financial cost advantages and may increase reserve holdings. We assess the liquidity ri...

U.S. Day-Ahead Markets (DAMs) for wholesale electric power managed by Independent System Operators (ISOs) encompass more than 60% of U.S. generating capacity. The current design of these DAMs encourages a focus on decisions that minimize immediate net costs without explicit consideration of pre-DAM and post-DAM decision opportunities. This study proposes a practical DAM reformulation that enabl...
